![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 (CĄHGO4) 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-1 °C•!.
The combustion enthalpy is –1675 kJ/mol dimethyl oxalate.
C,H,O4(s) + 7/2 O2(g -
→4 CO2(g) + 3 H20(1) A,H° = -1675 kJ/mol
