Mothballs are composed primarily of the hydrocarbon naphthalene (c10h8). When 1. 025 g of naphthalene (m. W. = 128. 17 g/mol) burns in a bomb calorimeter, the temperature rises from 24. 25 oc to 32. 33 oc. Find for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5. 11 kj/oc. Recall that is the heat corresponding to the stoichiometry of the reaction.
