Module Seven Part F: Calorimeter Problems 5 points

Benzoic acid (C₆H₅COOH) is sometimes used as a standard to determine the heat capacity of a bomb calorimeter (constant volume). The calorimeter is an insulated containing with 1.20 kg of water. When 1.32 g of benzoic acid is burned in a calorimeter that is being calibrated , the temperature rises from 20.93 ^oC to 22.93 ^oC. What is the heat capacity of the calorimeter? The heat of combustion of benzoic acid (q_v) is -26.42 kJ/g capacity of the calorimeter? The heat of combustion of benzoic acid (q_v) is -26.42 KJ/g
