In a coffee-cup calorimeter, 1.70 g of NH4NO3 is mixed with 76.0 g of water at an initial temperature of 25.00C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.71C. 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.
