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 0.5265 g sample of bisphenol A (C15H16O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.377×103 g of water. During the combustion the temperature increases from 21.79 to 24.65 °C. The heat capacity of water is 4.184 J g-1°C-1. The heat capacity of the calorimeter was determined in a previous experiment to be 841.7 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of bisphenol A based on these data. C15H16O2(s) + 18O2(g) 8 H2O(l) + 15 CO2(g) + Energy Molar Heat of Combustion = kJ/mol
