Question- The enthalpy of combustion of lactose, C12H22O11, is -5652 kJ/mol. A 2.50 g sample of lactose was burned in a calorimeter that contained 1350 g of water. The heat capacity of the calorimeter is 1630 J/oC, and the initial temperature was 24.58oC. What was the final temperature(oC)?(Atomic weights: C = 12.01, O = 16.00, H = 1.008).

Please answer only if you are 100% confident
