1.	The standard heats of formation ofCH_(4)(g), CO_(2)(g) and H_(2)O(g) are - 76.2, - 394.8 and -241.6 kJ mol^(-1) respectively . Calculate the amount of heat evolved by burning 1m ^(3) of methanemeasured under normal conditions.
Answer» Solution :1 mole of `CH_(4) = 22400 cm^(3) = 22400 xx 10^(-6) m^(3) = 2.24 xx 10^(-2) m^(3) .`
