How to find the overall heat capacity of a calorimeter?
Are there any equations or something I need to know for this? I'm thinking q = mcT, but I'm not so sure how to go about this.
For example, what should I do in:
The enthalpy of combustion of benzoic acid
(C6H5COOH) which is often used to calibrate
calorimeters, is −3227 kJ/mol. When 1.303 g
of benzoic acid was burned in a calorimeter,
the temperature increased by 2.054C. What
is the overall heat capacity of the calorime-
ter? The overall heat capacity includes the
calorimeter hardware and the water that is in
it.
Answer in units of kJ/C

I believe you determine moles of benzoic acid, then you can calculate how many joules were released and can determine the value by dividing joules the temperature rise.
3227kj/mole x (1.3033/122.12g/mole) = 34.43kj
34.43kJ/2.054C = 16.76kJ/C
