A sample of naphthalene (C10H8) that has a mass of 0.7200 g is burned in a bomb calorimeter. The mass of the calorimeter is 1.580 kg, and its specific heat is 2.55 J/(g C). As a result of the reaction, the temperature of the calorimeter increases from 22.00C to 29.3C. If 1 mol of naphthalene has a mass of 128.0 g, what is the molar heat of combustion of naphthalene?
11,300 kJ/mol
5,230 kJ/mol
3,760 kJ/mol
29.4 kJ/mol
