Thermometer 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. Ignition wires heat sample Stirrer In an experiment, a 1.1750 g sample of dimethyl oxalate (C4H604) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.146x103 g of water. During the combustion the temperature increases from 22.34 to 25.41 °C. The heat capacity of water is 4.184 ) g-loc-1. Water The heat capacity of the calorimeter was determined in a previous experiment to be 893.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of dimethyl oxalate based on these data.
