Calculate the enthalpy change when 50.0 grams of ammonium nitrate dissolves in 250 mL of water at 25°C. The initial temperature of water was also 25°C and the final temperature after dissolution was 18.5°C. The molar mass of ammonium nitrate is 80.04 g/mol and the specific heat of water is 4.184 J/g°C. Assume that the heat capacity of the solution is the same as that of water.
