A quantity of 1.435 g of naphthalene (C10H8), a pungent-smelling substanceused in moth repellents, was burned in a constant-volume calorimeter. Consequently, the temperature of the water rose from 20.280C tom 950C. If the heat capacity of the bomb plus water was 10.17 kJ/0C, calculate the heat of combustion of naphthalene on a molar basis; that is, find the molar heat of combustion.

Question
- A quantity of 1.435 g of naphthalene (C10H8), a pungent-smelling substanceused in moth repellents, was burned in a constant-volume calorimeter. Consequently, the temperature of the water rose from 20.280C tom 950C. If the heat capacity of the bomb plus water was 10.17 kJ/0C, calculate the heat of combustion of naphthalene on a molar basis; that is, find the molar heat of combustion.
