Two aqueous solutions are mixed in a constant-pressure calorimeter to produce a reaction. The calorimeter and solutions are initially at 22.0°C and the final temperature of the system was 16.0°C. If the calorimeter lost 395 J of heat and the water lost 2745 J, calculate the molar heat of reaction (molar qrxn; in kJ/mol) if 0.0278 moles of the limiting reagent react.
