The change in enthalpy for dissolving ammonium nitrate in water is 26 kJ/mol. Determine the amount of ammonium nitrate (in grams) that was dissolved in water to make 50.0 mL of solution if the temperature of a coffee cup calorimeter changes from 25.3°C to 21.5°C. Assume the density of the solution is 1.0 g/mL and the heat capacity of the solution is 4.2 J/g°C.
