A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.5540 g sample of 1,2-benzenediol (CgH,O2) is bumed completely in a bomb calorimeter. The calorimeter is surrounded by 1.068×10° g of water. During the combustion the temperature increases from 21.74 to 24.60 °C. The heat capacity of water is 4.184 J g-l•c!. The heat capacity of the calorimeter was determined in a previous experiment to be 782.4 J/^C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 1,2- benzenediol based on these data. C,H,O2(s) + (13/2) O,(g) → 3 H,O(1) + 6 CO2(g) + Energy Molar Heat of Combustion kJ/mol

Question
A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.5540 g sample of 1,2-benzenediol (CH,O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.068×10° g of water. During the combustion the temperature increases from 21.74 to 24.60 °C. The heat capacity of water is 4.184 Jglc. The heat capacity of the calorimeter was determined in a previous experiment to be 782.4 J°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 1,2- benzenediol based on these data. C,H,O,(s) + (13/2) 02(g) 3 H,O(1) + 6 CO2(g) + Energy Molar Heat of Combustion = kJ/mol
