The enthalpy of combustion of benzoic acid (C6H5CO2H) is –3228 kJ/mol. The burning of 1.698 g of benzoic acid in a calorimeter causes the temperature to increase by 2.865 ºC. What is the heat capacity (in kJ/ºC) of the calorimeter?

mols benzoic acid = grams/molar mass = ?
Then q = mols benz acid x Ccal(delta T)
q is +3238 kJ. Substitute and solve for Ccal.
