Question

A lighter-than-air balloon contains 1005 mol helium at
1.00 atm and 25.0°C.
(a) Compute the difference between the mass of the
     helium it contains and the mass of the air it displaces,
     assuming the molar mass of air to be 29.0 g mol-1 .
(b) The balloon now ascends to an altitude of 10 miles,
     where the temperature is - 80.0°C. The walls of the
    balloon are elastic enough that the pressure inside it
    equals the pressure outside. Repeat the calculation of
    part (a).
