Homework Help: Chemistry

Posted by Monique on Tuesday, October 18, 2011 at 12:50am.

How many moles of gas must be forced into a 3.5 L ball to give it a gauge pressure of 9.4 psi at 25 degrees C? The gauge pressure is relative to atmospheric pressure. Assume that atmospheric pressure is 14.7 psi so that the total pressure in the ball is 24.1 psi
Ok so I'm doing PV=nRT solving for n. PV/RT

So I'm converting psi to atm but I'm confused what is all the extra info given. Isn't it 9.4 psi / 14.7 psi x 1 atm
