In a coffee-cup calorimeter, 1.56 g NH4NO3 is mixed with 75.0 g water at an initial temperature of 25.22°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.36°C. Assuming the solution has a heat capacity of 4.18 J/°C-g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
