q = mass x Ccal x (Tf-Ti)
q = 2.85 x Ccal x (29.19-24.05)
Solve for Ccal. You will need to look up the value of q which is the heat of combustion for benzoic acid and substitute that for q. Note that heat of combustion is - but this heat is being added to the calorimeter so change the sign to + for the q value.
When 2.85 g of HC7H5O2 (molar mass = 122.12 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter changed from 24.05 ºC to 29.19 ºC. What is the heat capacity of the calorimeter in units of kJ/ºC?
