A 1.000 g sample of octane (C8H18, molar mass = 114.23 g/mol) is burned in a bomb calorimeter containing 1200 grams of water at an initial temperature of 25.00 °C. After the reaction, the final temperature of the water is 33.20 °C. The heat capacity of the calorimeter is 837 J/°C. The specific heat of water is 4.184 J/g °C. Calculate the molar heat of combustion of octane in J/mol.
