Problem: A 15.0-L tank is filled with He to a pressure of 2.00 x 102 atm. How many balloons (each 2.00 L) can be inflated to a pressure of 1.00 atm from the tank? Assume that there is no temperature change and that the tank cannot be emptied below 1.00 atm pressure.

Given:

V1 = 15.0 L
P1 = 2.00x102 atm
V2 = ?
P2 = 1 atm

Remember the ideal gas law: PV = nRT

Assuming the amount of He will remain constant, T is constant and R is also a constant.

PV = nRT
