heat of combustion

[Ms. Anne]

Hello, 

 

I am working through my chemistry homework and hoping someone can tell me if I am on the right track or not. 

Q:  

   A 0.500g sample of naphthalene (C10H8) is burned in a bomb calorimeter containing

    650g of water at an initial temperature of 20.00oC.  After the reaction, the final

    temperature of the water is 26.4oC.  

    The heat capacity of the calorimeter is 420 J/goC.  

    Using this data, calculate the heat of combustion of naphthalene in kJ/mol
