Suppose you burned 1.634 g of benzoic acid, C6H5 CO₂ H, in a constant volume calorimeter and found that the temperature increased from 20.01 °C to 30.63 °C. The calorimeter contained 721 g of water, and the bomb had a heat capacity of 876 J/K. Calculate AU per mole of benzoic acid. Specific heat of water is 4.184 J/g · K. . Benzoic acid, C6H5 CO₂H, occurs naturally in many berries. Its heat of combustion is well known, so it is used as a standard to calibrate calorimeters. AU = | kJ/mol C6H5 CO₂ H
