I have no clue how to figure this problem out..

The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.90×105 ft^3 of helium. If the gas is at 24 degrees Celsius and 1.0 atm, what mass of helium is in the blimp?

  • chemistry hw please help -

    PV=mass/molmassHe * RT
    solve for mass.

    I would start by changing ft^3 to m^3
