for combustion of naphthalene is -5164 kJ/mol
Explanation:

where, C refers heat capacity and
refers change in temperature.
Here, 
So, 
is generally expressed in terms of per mole unit of reactant. Also,
should be negative as it is an exothermic reaction (temperature increases).
Molar mass of naphthalene is 128.17 g/mol
So, 1.025 g of naphthalene =
of naphthalene
= 0.007997 moles of naphthalene
