3. A 0.500 g sample of n-heptane(1) burned in a constant volume calorimet o CO:(g) and H;0(1) causes a temperature rise of 2.934°C. If the heat capaci I the calorimeter and its accessories is 1954 cal/°C, and the mean temperatu i the calorimeter is 25°C, calculate: (a) The heat of combustion per mole of the heptane at constant volume (b) The heat of combustion of the heptane per mole at constant pressure.
