heat of combustion?

Question

Can anyone help me out with this question??
The heat capacity of a bomb calorimeter is determined to be 5.718 kJ/C. 1.350g of lactic acid (HC3H5O3) is burned. The temperature of the calorimeter increases from 24.00 C to 27.59 C as a result of this combustion. Calculate the heat of combustion per mole of lactic acid.

Answer 1

(5.718 kJ/C)*(27.59C - 24.00C)*(90.08 g/mol) /(1.350g)
You do the mass and the unit is kJ/mol.
90.08 g/mol is the molar mass of lactic acid.
