A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of 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 0.436-g sample of heptadecanoic acid (C17H34O2) in a bomb calorimeter containing 1100. g of water. The temperature increases from 25.40 °C to 28.50 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −10620 kJ per mole of heptadecanoic acid. C17H34O2(s) + 49/2 O2(g) ------> 17 CO2(g) + 17 H2O(l) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = J/°C
