A rigid tank of 100 L contains equal volumes of liquid and vapor of refrigerant R12 at 35 C. We add R12 to the tank until the final mass of R12 inside the tank is 80 kg. If the temperature remains constant, what is the volume occupied by the liquid in the final state? How much mass of R12 was added to the tank?
