The standard enthalpies of formation, at 25.00\deg C, of methane (CH4(g)), water (H2O(1)), and carbon dioxide (CO2(g)) are, respectively, -74.6 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. What quantity of heat is released (in kJ) during the combustion of 18.20 L of methane under a constant pressure of 1.000 atm at 25.00 deg C (N.B., combustion is the reaction of a substance with molecular oxygen to produce water and carbon dioxide)?
