A bomb calorimeter is supplied with 25.0 kJ of energy, and a 1.75 oC increase in temperature results. A 0.035 mole sample of an unknown fuel is combusted in the same bomb calorimeter, and qfuel is found to be -6290 kJ/mol. What temperature change occurred when the fuel was combusted in the bomb calorimeter
