A party supply store sells a helium gas cylinder with a volumeof 1.55 X 10-2m3 . If the cylinder provides 1.81m3 of helium forballoon inflation (at STP), what must be the pressure insidethe cylinder? I have tried to figure this out and I just can't get it..Please help me with this. A party supply store sells a helium gas cylinder with a volumeof 1.55 X 10-2m3 .

Explanation / Answer
The way to answer this is to manipulate the ideal gasequation: PV = nRT Since the nRT is constant (because number of molesdoesn't change, R is a constant and T doesn't change), P1V1 = nRT =P2V2
