Naphthalene (C10H8), which has a heat of combustion equals to -5183 kJ/mol was used as standard

in a bomb calorimeter. When 0.50 g naphthalene was burnt, the water inside the BC was increased by 0.51C. When a pill weighing 0.75 g of aspirin (M = 180.12 g/mol) was burnt, the temperature increased by 0.25 C.

a) Find the heat capacity of the calorimeter

b) Determine the molar heat evolved from the aspirin sample
