The heat of solution of ammonium chloride is 15.2 kJ/mol.  If a 6.134 g sample of NH₄Cl is added to 65.0 mL of water in a calorimeter at 24.5°C, what is the minimum temperature reached by the solution? (The specific heat of water = 4.18 J/g·°C; the heat capacity of the calorimeter = 365. J/°C.)

▸ 18.6°C

▸ 19.7°C

▸ 21.9°C

▸ 27.1°C

▸ 30.4°C
