under constant-volume conditions the heat of combustion ofbenzoc acid (C7H6O2) IS 26.42kJ/g. a 01.854-g sample of benzoic acid is burned in a bombcalorimeter. The temperature of the calorimeter is increasedfrom 25.02oC to 27.56oC. What is the totalheat capacity of the calorimeter. under constant-volume conditions the heat of combustion ofbenzoc acid (C7H6O2) IS 26.42kJ/g. a 01.854-g sample of benzoic acid is burned in a bombcalorimeter.

Explanation / Answer
We Know that : The Combustion of the benzoic acid givesfollowing product. C6H5COOH + 15/2 O2 -------> 7CO2 + 3 H2O + Energy Q = m s t = 26.42 KJ / g x 0.1854gm / 2.54 0C s = 1.928 KJ / 0C
