Standard heat of formation of `CH_(4),CO_(2)` and `H_(2)O_((g))` are `-76.2,-394.8` and `-241.6kJ mol^(-1)` respectively. Calculate the amount of heat evolved by burning `1m^(3)` of `CH_(4)` measured under normal conditions.

Answer

`35694.6kJ`

Explanation

1 mole of `CH_(4) = 22400 cm^(3) = 22400 xx 10^(-6) m^(3) = 2.24 xx 10^(-2) m^(3) .`
