The complete combustion of methane has a reaction enthalpy of -861.3 kJ/mol, according to the following equation: CH4(g) + 2 O2(g) –> CO2(g) + 2 H2O(l) ΔHrxn = -861.3 kJ/mol Calculate the enthalpy for the combustion of grams of methane. Give your answer in kJ, and be careful of the sign and significant figures.
