A) M^2 s^-1

B) M^-2 s^-1

C) s^-1

D) M s^-1

E) M^-1/2 s^-1

1) If you do not completely dry off the flask after allowing the vapor to condense, this will give you a calculated molar mass that is:

A. unchanged from the true molar mass of the unknown

B. lower than the true molar mass of the unknown

C. higher than the true molar mass of the unknown

2) If you have a badly calibrated thermometer, and the temperature of the water bath reads 96.3oC instead of the true 100.0oC, using this incorrect lower temperature will give you a calculated molar mass that is:

A. unchanged from the true molar mass of the unknown

B. lower than the true molar mass of the unknown

C. higher than the true molar mass of the unknown

For every 1.00 mol of NH3 that reacts, how many mols of O2 is required?

Yay college math placement exams! -___-

This problem just started occuring today. I tried plugging in my USB to charge my phone and when I did, NOTHING happened. No pop-up message at all. I'd plug it in and that's all. What the helll is going on? It's a Toshiba Satellite L505

Mostly American foods with good entrees and desserts! Thanks.

I need any suggestions for religious Christian songs to sing in front of a congregation for my anniversary next month. Thanks in advance!

L.A. BABYY!

Besides a BJ?

I type with 2 lol.

My brother has a computer in his room along with a chair. Uh it's made out of some fabric, and it's blue. On the place where your legs part, there are splotches of dry white stains on it. Is this what I think it is?

And I've caught him on porn sites one too many times. LOL I DON'T WANT THIS TO BE WHAT I THINK IT IS.

In front of a church mass.

with a sexy Southern accent.

Feel the need to list every single ethnic background they THINK they're from?

Like you'll ask what they are and they'll give you about 6 different countries.

And yes, I'm aware I'm white.
