Answer:

-369.57KJ

Explanation:

Details are contained in the image attached.

First we obtain the molar mass of ethanol C2H5OH=46gmol-1. Then we put down the balanced chemical reaction equation for the combustion of ethanol. Knowing that the molar heat capacity of ethanol is -1360KJ, we apply it to obtain the heat from burning 12.5g of ethanol. Hence the answer.
