1. You used a bomb calorimeter, or constant-volume calorimeter, but misplaced the information of heat capacity of the calorimeter. If you burn 1.250 g of an organic compound, with, ΔE = -24.30kJ/g, and measured a temperature change from 25.00oC to 47.60oC, what must the heat capacity of the calorimeter be?
