A two-phase liquid–vapor mixture of Refrigerant 134a is contained in a 2-ft3, cylindrical storage tank at 100 lbf/in.2 Initially, saturated liquid occupies 1.6 ft3. The valve at the top of the tank develops a leak, allowing saturated vapor to escape slowly. Eventually, the volume of the liquid drops to 0.6 ft3. If the pressure in the tank remains constant, determine (a) the mass of refrigerant that has escaped, in lb, and (b) the heat transfer, in Btu.

PLEASE USE THE NUMBERs FROM THIS QUESTION. I am trying to compare my answers because I keep getting it wrong. Thank you

Refrigerant 134a, initially (state 1) a saturated liquid at -80C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. The change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature. If the mass of the refrigerant is 0.1 kg, determine (a) heat transfer using first law of thermodynamics in kJ...
