A 1.148 g sample of benzoic acid is burned in an excess of oxygen in a bomb calorimeter. The temperature of the water rises from 24.96�C to 34.75�C. The heat of combustion of benzoic acid is -26.42 kJ/g. In a second experiment, a 0.895 g powdered coal sample is burned in the same calorimeter embly. The temperature of the water rises from 24.98�C to 29.73�C. How many kilograms of this coal would have to be burned to liberate 6.00X10^9 kJ of heat?
