Dissolving NH4Cl(s) in water is endothermic with a heat of the solution of 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?

[specific heat of water = 4.18 J/g·°C; heat capacity of the calorimeter = 365. J/°C]

1. 27.1°C

2. 18.6°C

3. 19.7°C

4. 21.9°C

5. 30.4°C

Having some trouble with this one. Would really appreciate an explanation of how to do it
