A coffee-cup calorimeter is calibrated by adding 1840 J of heat to the water in the calorimeter and measuring a 1.72C rise in temperature. When some NH4NO3(s) is added to the same water in the calorimeter, the temperature falls by 1.04 C. Calculate the enthalpy change due to the dissolving of this NH4NO3?
