A spherical helium balloon of 22 t in diameter is at ambient T and P, 60 F and 14.69 psia.How much helium does it contain? It can lift a total mass that equals the mass of displaced atmospheric air. How much mass of the balloon fabric and cage can then be lifted? ( R of Helium = 386 ft-lbf/lb degR , R of air 53.34 ft-lbf/lb degR )

Question

A spherical helium balloon of 22 t in diameter is at ambient T and P, 60 F and 14.69 psia.

How much helium does it contain?
