(a) The accurately known molar heat of combustion of naphthalene, C 10 H 8 (s), H =- 5156.8 kJ/mol C 10 H 8 ,

(a) The accurately known molar heat of combustion of naphthalene, C₁₀H₈(s), ΔH =-5156.8 kJ/mol C₁₀H₈, is used to calibrate calorimeters. The complete combustion of 0.01520 g of C10H8 at constant pressure raises the temperature of a calorimeter by 0.212°C. Find the heat capacity of the calorimeter. 

(b) The initial temperature of the calorimeter (part a) is 22.102°C; 0.1040 g of C₈H₁₈(/), octane (molar heat of combustion ΔH = -5451.4 kJ/mol C₈H₁₈,) is completely burned in the calorimeter. Find the final temperature of the calorimeter.
