A balloon filled with 31.9 mol helium has a volume of 715. L at 0.0°C?

A balloon filled with 31.9 mol helium has a volume of 715. L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 68.0°C as it expands to a volume of 893. L, the pressure remaining constant. Calculate q, w, and E for the helium in the balloon. (The molar heat capacity for helium gas is 20.8 J/°C·mol.)
