The combustion of 0.1583 g benzoic acid increases the temperature of a bomb calorimeter by 2.93C. Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 kJ/g.)

A 0.1710 g sample of vanillin (C8H8O3) is then burned in the same calorimeter, and the temperature increases by 3.25C. What is the energy of combustion per gram of vanillin?

What is the energy of combustuin per mole of vanillin?
