[Solved] The standard enthalpies of formation, at 25.00 oC, of methane (CH4(g)), water (H2O(l)), and carbon dioxide (CO2(g))

The standard enthalpies of formation, at 25.00 oC, of methane (CH4(g)), water (H2O(l)), and carbon dioxide (CO2(g)) are, respectively, -74.6 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. Calculate the amount of heat released (in kJ) during the combustion of 18.89 L of methane under a constant pressure of 1.000 atm at 25.00 oC (N.B. combustion is the reaction with molecular oxygen to produce water and carbon dioxide.)
