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 0.3460 g sample of bianthracene (C28H]) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.124x103 g of water. During the combustion the temperature increases from 23.46 to 25.85 °C. The heat capacity of water is 4.184 Jg-loc-1 The heat capacity of the calorimeter was determined in a previous experiment to be 807.9 J/ °C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of bianthracene based on these data. C28H18(s) + (65/2) 02@– 9 H2O(1) + 28 C02() + Energy Molar Heat of Combustion = kJ/mol
