Chemical Thermodynamics Help?

The total volume of gas needed to fill the Hindenburg was 2.00X10∧8 at 1 atm and 25.0 degrees Celsius. How much energy was evolved when it burned?

H2(g) + (1/2)O2(g) --> H2O(l) ΔH= -286 kJ

    1 mol gas has a vol. of 22.4 L at S.T.P.

    So mol in 2 x 10^8 L at 25C = 8.18x10^6 mol

    Combustion of 1 mol gives 286 kJ

    combustion of 8.18x 10^6 will give 2.34x10^9kJ
