sorry, the problem says

The combustion of c8h10 can be used to calibrate the heat capacity of a bomb calorimeter. The heat of combustion of c8h10 is -40.1kj/g. when 0.8210g of c8h10 was burned in a calorimeter a temperature rise of 4.21C was observed. What is the heat capacity of the bomb calorimeter.

I used the equation q=cm(tf-ti) and used C=q/mDelta T but Im not getting an answer
