Homework Help: Chemistry

Posted by Luis on Friday, March 30, 2007 at 1:32am.

You have two gas-filled balloons, one containing He and the other containing H2. The H2 balloon is twice the size of the He balloon. The pressure of gas in the H2 balloon is 1 atm, and that in the He balloon is 2 atm. The H2 balloon is outside in the snow (−5 C), and the He balloon is inside a warm building (23 C).
(a) Which balloon contains the greater number of molecules?
(b) Which balloon contains the greater mass of gas?

WEll, the warmer balloon is expanded from the cold, so it at the same PV must have lesser moles of gas.
