A bomb calorimeter whose components have a heat capacity of 6.66 kJ/°C is filled with 913 g of water. (The amount of water is not constant from experiment to experiment. The heat capacity of the calorimeter is broken down into two parts: the water and the calorimeter components.) The initial temperature of the calorimeter contents is 21.81°C. A 1.132 g sample of benzoic acid (ΔEcomb = -26.42 kJ/g) is combusted in the calorimeter. What is the final temperature of the calorimeter contents?
