21 AnswersPolls & Surveys5 years agoChemistry The vapor pressure of ethanol is 100mmhg at 34.9 C. What is its vapor pressure at 65.5 C? Hap for ethanol is 39.3 Kj/mol?
Equation: IN p1/p2= hvap/R (T1-T2/T1T2)
P1: 100 mmHg P2: ?
T1: 65.5C + 273 = 338.7K
T2: 34.9C +273=308K
In (100mg/P2) = 39.300J/mol/8.314 J/K mole {(308K-338.7K)/308*338.7)}
= -1.39
100/P2= e^-1.39= .249
What is P2?
I can get this far but I don't know what else I should do. I also have to use a basic calculator so if you could tell me what button to push that would be great.
This is what the calculator looks like
1 AnswerChemistry5 years agoSo emotional over things that haven't even happen yet!?
Sometimes when I am in my car alone or lying in bed trying to go to sleep I come up with these what if scenarios in my head and I end up bailing by eyes out.
Like for instances I was lying in bed and all of a sudden I started thinking about my cousin. He is a troubled kid who has had a pretty tough life. I kept thinking that what if hung himself. I started going into detail about who would show up to his funeral how I would feel ect. Before I know it I am bailing my eyes out and if someone saw me and ask what was wrong what could I tell them without sounding crazy. I do the same thing with my grandmother dying. Am I the only person that does this?
