When a 3.17 g sample of liquid octane (C8H18) is burned in a bomb calorimeter, the temperature of the calorimeter rises by 27.6 °C. The heat capacity of the calorimeter, measured in a separate experiment, is 6.11 kJ/°C. The calorimeter also contains 3.00 kg of water, with a specific heat capacity of 4.18 J/g°C. Determine the ΔE of combustion of octane in units of kJ/mol octane. Enter your answer numerically and in terms of kJ/mol.
