The combustion of 0.1590 g benzoic acid increases the temperature of a bomb calorimeter by 2.51°C.
Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 kJ/g.)
Heat capacity = 1.66 kJ/°C A 0.2120-g sample of vanillin (C₃H₂O₃) is then burned in the same calorimeter, and the temperature increases by 3.28°C.
What is the energy of combustion per gram of vanillin ?
Energy = 25 kJ/9
Per mole of vanillin ?
Energy = 384 kJ/mol
