1. Propane (C3H8 (g)) burns in oxygen to produce carbon dioxide and water. When 14.64 g of propane is burned in an excess of oxygen in a calorimeter at 25⁰C and atmospheric pressure, 678.6kJ of heat is evolved. Calculate the standard enthalpy of formation of propane. The standard enthalpies of formation of CO2 (g) and H2O (g) are -393.51 kJ/mol and -241.82 kJ/mol respectively.
