The combustion of naphthalene (C10H8), which releases 5150.10 kJ/mol of energy, is used to calibrate calorimeters. A 1.05-g sample of naphthalene is burned in a calorimeter producing a temperature rise of 3.86 °C. Burning a 1.83-g sample of coal in the same calorimeter causes a temperature change of 4.90 °C. What is the energy density of the coal?
