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 0.6770 g sample of quinizarin (C14H3O4) is burnmed completely in a bomb calorimeter. The calorimeter is surrounded by 1.304x10° g of water. During the combustion the temperature increases from 25.97 to 28.55 °C. The heat capacity of water is 4.184 J gl°c!. The heat capacity of the calorimeter was determined in a previous experiment to be 893.2 J°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data. C1,H3O4(s) + 1402(g)→ 4 H,O(1) + 14 CO2(g) + Energy Molar Heat of Combustion = kJ/mol
