Pi= MRT

so simplified down it is

pi= (mass/(MW * liter)) *RT

How do I rearrange the equation to solve for molecular weight (MW)?

i started to feel my throat scratchy monday night, then throughout the night as i slept, i started to get a really high fever. so, my mom let me miss school. the fever on tuesday was accompanied by sore throat, headache, congestion, and aching of the body. this went on till wednesday where i missed school again. then yesterday, (thursday) i went to the doctor to see what was up and she told me that she wasn't gonna prescribe antibiotics to me. i mean i thought it was the flu at first but i don't think flus last for 5 days! i woke up today with a cough. i'm not really sure how to make myself better-- i've already missed like a week of school and i can't afford to miss any more. i plan on going back to school on monday so i have the weekend to get better. any recommendations ? over the counter medications ? i've alternated between tynenol and motrin for fever and dayquil/nyquil for the sore throat, congestion, headache, etc. i also know to get rest and drink lots of fluids. i've been doing that.

as stated above, he's really smart. he had just recently joined the gifted/magnet program at my school after taking regular classes his whole life, so it was kind of a shock for him when he got into this program- seeing the tremendous amount of work and difficulty of the classes. it's a big step up. i understand that. however, after being in the program for a semester, he still doesn't want to put forth the effort. he's really intellectual, he just doesn't show his full potential and apply himself in school. i want to send him a message that would- oh i don't know, maybe inspire him to give 100% in all his work. i really want him to do well. any suggestions on what i should say?

i started p90x yesterday. im 14 years old and 136 pounds so im trying hard to lose my tummy fat mainly and my curves are totally out of control. im trying to not feel discouraged because i couldnt keep up with the trainors in the video...but they are fit and in shape and ive only been doing p90x for 2 days. so, again im trying to not feel bad since i couldnt do some of the exercises and keep up. although, i have tried my best to do what i can. and my body ACHES! all over. my arms, my chest, my sides, my abs, my thighs, my calves. everything aches. i cant even get up it hurts so bad. i know that i should suck it up since i just started working out, but i just wanted to know if you guys know what helps with the aching and soreness.

i didn't buy the workout program from the tv offer. i'm downloading it online, and it's taking forever but i don't have 200 bucks to spend on this program. anyways, i'm not obese for starters. i am overweight, though. i'm 14, 5'1, and i weigh 136 pounds. i know i shoulda accept my body the way it is, but my self esteem has lowered a bit because of my body. i couldnt fit into half of the clothes that i tried on when i went to the mall on friday, and it was embarrasing because i had a group of friends come with me. i have no exercise equipment except two 6 pound dumbells. and my mom isnt planning on buying anything. i want to eat healthy, but i'm indian, and the food we make involves a lot of rice, which can obviously store up as fat. i just want my goal weight to be about 120 pounds, so 15-16 pounds is all i want to lose. i am a gifted student, so i might have to cut the workouts in half each day because of all the schoolwork i have. i basically want to lose about 15-20 pounds by june, so in about 2 months. i don't plan on using the nutrition guide, either. i know if i want it to work, i have to follow it exactly. but i don't want to be super duper skinny like the people on the p90x commercials. so would this work for me?

i'm 136 pounds and im 14 years old. the ideal weight for 14 year olds is about 120, which is what my doctor told me. i'm not that motivated to go out and run...and i dont have any exercise equipment besides two 6 pound dumbells. i have BIG muscles in my arms because i used to play volleyball but the rest is fat,making my arms look huge! i don;t wanna order any weight programs from the tv, either. i just want to lose 16 pounds by this summer. any suggestions? i'm defff gonna try to cut out the fatty foods, or maybe lessen it to having something fatty maybe once a week. i have some bad curves and my stomach pops out...not tooooo much but its really visible! my thighs arent so much toned, either. how can i lose 16 pounds?

i have used pantene, head and shoulders, garnier fructis, suave, and herbal essences and none of them seem to work. i take a shower every other day and my hair gets oily the next morning... and i take showers at night. my hair is thick after a shower and i have naturally black hair. i often like to straighten my hair once or twice a week and blow dry it maybe once a week. i have been trying to cut down on the heat i put on my hair- not sure if that plays a part into making my hair oily so quickly. i know i have split ends and my hair is semi-long it goes right below the shoulders and i dont plan on getting a haircut anytime soon. i'm just looking for a good 2 in 1 shampoo+conditioner to use that at least leaves moisture in my hair for 2 days instead of oil. i don't want to make my hair any thinner because it has already become thin since i have been using my straightener...but i don't want it fully volumized either. what would you suggest? i'm 14 by the way.

ok so i tried out for the jv team. and i admit i am pretty short, 5'2. i didnt make the cut and my mom was so surprised so was i! i am like the best setter nd server nd i thought i did my best yesterdy- i was literally on fire. then my mom called the coaches and they said i didnt make it cause i was short!!! if they had a problem with my height, my bakrow passing isnt bad either! i understand i cant block in the front row n all as to bein a setter, but then i feel so stupid cause my family has wasted their money and i have wasted my time for a team tht bases you on your height.if i had known that, i wouldnt have started playing at all. and last year, tey had no problem taking me n forthe middle school team. i was the shortest one there, but there were girls who didnt even play at all and just started this summer- they made the cut. they havnteven seen a vball and they are prolly gonna make the team. i have been playing vball for 2 years and i feel its not fair. my mom said some very bad things to the coaches because she knows i am a really good player nd i have so much team spirit. and there were girls who just showed up to tryouts yesterday when they started like 3 days ago! thts not fair to everyone else who has bee so sore from tryouts. that they just showed up and made the cut. i dont kno if i wanna play for a team like that who is so concerned about height. cause i cant do anything to change my height!! i wanna continue playing vball but club is just too expensive for us and my high school team didnt take me cause im short. do u think this is fair? what should i do?

hey i am goin to be a freshman this year and this week is our school tryouts for the jv team. we just started monday and i am soooo sore! we did suicides like 20 times and yesterday wasnt so bad i was jus so sore from monday. i played on my middle school team last year though.. but tryouts continue today and is there any way to like get rid of the soreness? i dont wanna play bad today since today is when they decide the team! they start in a few hours and can anyone give me some tips on how to make the soreness go away soon, even the slightest bit?

ok so i was on the team last season nd i havent played vball since october. well i wana make the team this fall so yesterday i went to the vball gym to play and i felt like i lost some of my skill from when i played last year. i was a setter nd my setting was way off, my serves were out of the court, nd my passing was not right.i made a club team, but my mom thought it was a waste of money so i didnt play since then. ever since yesterday my body has been aching so much i cant move my shoulder my chest hurts when i breathe, my thighs feel like crap and my muscles are so sore. is it because i havent played for awhile? i mean practice yesterday wasnt as rigorous as my practices back in the fall; we barely did any drills! so is this normal to feel like crap just after one practice?

and also, what should i do to feel better or to make the pain go away cuz i have plans tommorow nd i dont wana feel like crap :(

My blood began to boil...is this an example of personification or alliteration?

i love vball...its my life..or was my life. i made 2 club teams this season a month ago but my mom didnt wanna pay for it. so i didnt play club...i was the setter for my team and i did so well at the tryouts it was unbelieveable! anyways, im starting to get jealous of a girl who made the same school team as me and the same club team. she actually got moved up to the higher team too! im 13 and 8th grader so i play for a middle school team. so the varsity needs a libero next year cuz theirs is graduating and the girl who im jealous of wants to take place on the varsity! she was our libero and im so mad at my parents cuz i wanted this so badly...now i dont even think ill make the jv team cuz there are only like 4-5 spots open and we have about 9 8th graders on our team! idk wat to do..im afriad ill lose my vball skills and touch by tryouts next august..wat should i do? and sitting out for club this season has made me even more depressed

My parents keep leturing me that I can't tryout for any more club because they've already spent 70 bucks on te tryout fees for 2 clubs I tried out for. The thing is that the first club I tried out for- The head coach was my assistant coach for my team this season and she did not like me at all! She never let me play nor never talked to me. I've heard that this is a good club but it's 1.8 thousand for one season! My mom said she's not gonna pay that much. Then, the second club I tried out for- The tryouts were 2 days ago and they weren't organized at all! One of the coaches also started to get on my nerves and I've heard that this is an ok club, it's not as good as the first club I tried out for. This cost is around 1.6 thousand.

See I want to tryout for another club to see if I can get things cheaper, but my mom refuses to take me! And the tryouts are today! I've already went online and submitted my registration form. I've talked to JV players (btw I'm in the 14s group) and they said that there is this good club and tryouts are today.

For the first club, theyve already decided half the team and I'm becoming intimidated because the coaches (including the head coach who doesnt like me) said that the 6 they pick are the people that they know they want on the court all the time. If I get picked, I will barely play! So you know I'm caught....Idk what to do! I love volleyball so much but there are so many obstacles in the way of letting me play this season as to I'm preparing for JV or varsity next year (my parents,the coaches, the fees, and the distance from here its like 20 miles!)

im an 8th grade S/DS on my team and my mom is killing me about making varsity next year. she wants me to make it straight on to varsity and skip jv. thats possible because in the last 2 years, two freshmen made varsity. one really good setter and one tall tall tall MH/B. the problem is that if the 9th grade setter remains at the same school, she'll be setter throughout her whole high school year because shes really good at it. i am too, but my coach never realizes it. anyways, my mom wants me to take a few private lessons from an assistant coach that taught our varsity team last year (doesnt anymore i dont think) but i wanna play club vball. i want to make some team that i can play year round so that im up to date with my skills and the freshman played club vball too. what do you think would be best? i mean i will also try to take a camp and go to sessions too but which will help the most; private lessons or club? i wanna try out for 2-3 clubs so i can make atleast one and if i make more than 1, choose the one i think is best.

there is this question in my science book saying: How would you find the density of an unknown liquid if you have all the laboratory equipment you need?

I know how to find the density. D=M/V

i just dont know the tool used to measure mass of liquids. help!
