15.00 g of Compound X with molecular formula C,H10 are burned in a constant-pressure calorimeter containing 10.00 kg of water at 25 °C. The temperature of the water is observed to rise by 16.34 °C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) Calculate the standard heat of formation of Compound X at 25 °C. Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.
