A sample of 1.800 grams of octane, C8H18, was burned in a bomb calorimeter whose total heat capacity = 11.66 kJ/°C. The temperature of the calorimeter plus contents raised from 21.12°C to 29.85 degree Celsius. determine the heat of combustion per gram of octane and the heat of combustion per mole of octane?
