(a) When a 4.75-g sample of solid ammonium nitrate dissolves in 60.0 g of water in a coffee-cup calorimeter (see figure), the temperature drops from 23.0C to 16.6C. Calculate H (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.
