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 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...

Enter your answer in the provided box. The enthalpy of combustion of benzoic acid (CH COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol. When 3.0653 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84°C to 24.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2250 g.) kJ/°C
