A 2.05 g sample of palmitic acid (C16H32O2), a common constituent of fats, is burned in a bomb calorimeter. The temperature of the calorimeter increases by 31.6oC (Celsius). Given that the energy of combustion (?E) for palmitic is -39.2 kJ/g, calculate the heat capacity of the bomb calorimeter. Make sure you enter kJ/C for your unit behind the number.heat capacity of the calorimeter =
