If High purity benzoic acid [C6H5COOH; H(rxn) = -3227 kJ/mol] is a combustion standard for calibrating bomb calorimeters. If an unknown quantity of the benzoic acid is burn up in the calorimeter (heat capacity = 1365 J/C) containing exactly 800 g of water also results in a temperature increase of 5.62 C, explain how many moles of the benzoic acid was burned?
