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.
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
◦
C. What
is the overall heat capacity of the calorimeter? The overall heat capacity includes the
calorimeter hardware and the water that is in
it.
Answer in units of kJ/
◦
