A 3.24 g sample of lauric acid (C12H24O2), a common constituent of fats, is burned in a bomb calorimeter. The temperature of the calorimeter increases by 82.9oC (Celsius). Given that the energy of combustion (?E) for lauric is -37.1 kJ/g, calculate the heat capacity of the bomb calorimeter. Make sure you enter kJ/C for your unit behind the number.
