A tank of compressed helium for inflating balloons is advertised as containing helium at a pressure of 2374 psi, which, when allowed to expand at atmospheric pressure, will occupy a volume of 194 ft3. Assuming no temperature change takes place during the expansion, what is the volume of the tank in cubic feet?

P V = n R T
so
P1 V1 = P2 V2

2374 V1 = 14.7 * 194
