Ammonium nitrate sometimes is used in cold packs because its enthalpy of solvation in water is +21 kJ/mol. What is the minimum amount of ammonium nitrate (80.05 g/mol) that is needed to cool a 1.0 L soft drink (d = 1.0 g/mL, specific heat 4.5 J g^-1 ) and its plastic bottle (heat capacity 50 J/K) from 30 to 5 .
