When a 3.90-g sample of solid ammonium nitrate dissolves in 60.0 g of water in a coffee-cup calorimeter, the temperature drops from 24.5C to 19.3C. Calculate DH (in kJ/mol NH4NO3) for the solution process

NH4NO3(s) ---> NH4+(aq) + NO3-(aq)


Assume that the specific heat of the solution is the same as that of pure water.
