A compound is burned in a bomb calorimeter that contains 3.50 kg of water. If thecombustion of 0.215 moles of the compound causes the temperature of water toraise 17.0 C, what is the molar heat of combustion of the compound? The specificheat of capacity of water is 4.184 J/g C. The answer needs to be in kJ/mol and haveO decimal places.Your Answer:Answer
