y'all i got 7 minutes left on this test does anybody know how to do this??

When 1.68 grams of butylbenzene (C10H14) is combusted in a calorimeter that contains 1500. grams of water, the temperature of the water increases by 11.6oC. The specific heat of water is 4.184 J/ g oC. The molar mass of butylbenzene is 134.24 g/mol. What would be the heat change of butylbenzene in kilojoules.

oh shit it's only 5 minutes now fuck
