A 1.250 g sample of Octane (C8H18) is burned in excess of oxygen in a bomb calorimeter. The temperature of the calorimeter rises from 294.05 K to 300.78 K. If heat capacity of the calorimeter is 8.93 KJ/K. Find the heat transferred to the calorimeter. Also calculation the enthalpy of combustion of the sample of octane.
