Calculate the enthalpy change for the combustion of methane gas (CH4) if 37.0 g of CH4 is completely burned in a bomb calorimeter and the temperature increases by 285.4 K. Assume that the calorimeter has a heat capacity of 4.40 kJ/K and that the combustion reaction is as follows: CH4(g) + 2O2(g) -> CO2(g) + 2H2O(l); ΔH=-890.4 kJ/mol. What is the enthalpy change for the combustion of one mole of methane gas?
