Benzoic Acid Is Used to Determine the Heat Capacity of Bomb

question 80

Short Answer

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form, and its energy of combustion is known very accurately (26.43 kJ/g). Determine the heat capacity of a calorimeter that had a temperature increase of 8.199°C when 2.500 g of benzoic acid was used.
