2.14 grams of a mystery substance of food with a molar mass of 167.85 g/mol is burned in a bomb calorimeter. The water in the bomb calorimeter absorbs 178,468 Joules from the burning of the substance. Calculate the heat of combustion of the mystery substance in kJ/mol. (Please input your answer as a negative number.) (DO NOT PUT UNITS IN YOUR ANSWER.) Assume that all of the heat lost by the substance is transferred to the water and no heat is lost to the surroundings.
