Homework Help: Chemistry

Posted by Eric on Sunday, September 27, 2009 at 11:56pm.

You have a 22L cylinder of helium at a pressure of 150atm and a temperature of 31C. How many ballons can you fill, each with a volume of 5.0L, on a day when the atmospheric pressure is 755mmHg and the temperature is 22C?

I know I use PV=nRT, but what numbers do I plug in and why couldn't I use p1v1/t1=p2v2/t2?
