Homework Help: Chemistry 101

Posted by Madison on Tuesday, November 24, 2009 at 10:04pm.

Are these correct?
1. A sample of gases contains three gases at the following pressures: 1.2 atm N2, 3.2 atm O2, and 0.56 atm Xe. What is the total pressure in the container?
a. 5.0atm
b. 1.4atm
c. 2.2atm
d. 1.0atm
e. 1.7atm
I am pretty sure it is A. Is that correct?

2. The molar volume of a gas at STP
a. is always 22.4L
b.varies with the type of gas
c. is dependent upon the temperature and pressure of the gas
d. is directly proportional to the molar mass of the gas
e. is always 6.02 x 1023 L
I think this one is A as well.

Thank you for your help!
