Liquid ammonia (boiling point = -33.4 degrees Celsius) can be used as a refrigerant and heat transfer fluid. How much energy is neededto heat 25.0 g of NH₃ (liquid) from -65.0 degrees Celsius to -12.0 degrees Celsius ?

specific heat capacity, NH3 (liquid) 4.7 J/ (g x k)

specific heat capacity, NH3 (gas) 2.2 J/ (g x k)

Liquid ammonia, NH₃ (l), was once used in home refrigerators as the heat transfer fluid. The specific heat capacity of the liquid is 4.7 J/g•Kand that of the vapor is 2.2 J/g•K. The enthalpy of vaporization is 23.33 kJ/mol the boiling point. If you heat 12 kg of liquid ammonia from –50°C to its boiling point of –33.3°C, allow it to evaporate, and then continue warming to 0.0°C, how much energy must you supply?
