A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy available from foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.971-g sample of dimethyl oxalate (C4H,O4) in a bomb calorimeter containing 1050. g water. The temperature increases from 25.40 °C to 28.00 °C. The specific heat capacity of water is 4.184 J g-l °C*!. The combustion enthalpy is –1675 kJ/mol dimethyl oxalate. CĄHGO4(s) + 7/2 O2(g) 4 CO2(g) + 3 H2O(1) A,H° = -1675 k)/mol Calculate the heat capacity of the calorimeter.
