The enthalpy of combustion of benzoic acid
(C6H5COOH) which is often used to calibrate
calorimeters, is −3227 kJ/mol. When 1.402 g
of benzoic acid was burned in a calorimeter,
the temperature increased by 3.401
is the overall heat capacity of the calorimeter? The overall heat capacity includes the
calorimeter hardware and the water that is in
Answer in units of kJ/
How much heat did you put into the system. That will be (1.402g/molar mass benzoic acid) x 3227 kJ/mol = Ccal*delta T.
Solve for Ccal.
