Since it can be obtained in very high purity, benzoic acid is one of the classic materials used for determining the heat capacity of bomb calorimeters. the heat of combustion of benzoic acid, hc7h5o2 is -3227 kj mol-1. when 2.85 g of hc7h5o2 (molar mass = 122.12 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter changed from 24.05 Âșc to 29.19 Âșc. what is the heat capacity of the calorimeter in units of kj/Âșc?
