In a coffee-cup calorimeter, 1.80 g of NH_4NO_3 is mixed with 74.0 g of water at an initial temperature of 25.00 degree C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.07 degree C. Assuming the solution has a heat capacity of 4.18 J/g middot degree C and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
