Determine the standard enthalpy of formation of methane (CH4) given the following information: The standard enthalpy of formation of CO2 and H2O are -393.5 kJ/mol and -285.8 kJ/mol, respectively. The combustion of 0.50 g of methane in a bomb calorimeter resulted in a 1.20°C temperature increase of the surrounding water. The heat capacity of the bomb calorimeter is 5.85 kJ/°C.
