Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 0.820 g of naphthalene burns in a bomb calorimeter, the temperature rises from 25.10 °C to 31.56 °C. Find ΔErxn for the combustion of naphthalene. The heat capacity of the calorimeter is 5.11 kJ/°C. What is the value of ΔErxn in kJ/mol?
