The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.90×10^5 ft^3 of helium. If the gas is at 25 C and 1.0 atm, what mass of helium is in the blimp?

Convert 1.9 x 10^5 ft^3 to liters, use PV = nRT to solve for n, number of moles, and obtain grams from that. Then convert back to cubic feet is that is the desired unit.
