Question

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 0.466-g sample of 1,8-octanediol (C8H18O2) in a bomb calorimeter containing 1200. g of water. The temperature increases from 25.90 °C to 28.70 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −5094 kJ per mole of 1,8-octanediol. C8H18O2(s) + 23/2 O2(g) 8 CO2(g) + 9 H2O(l) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = ____J/°C
