A cylinder fitted with a movable piston contains water at 3 MPa, 50% quality, at which point

Question:

A cylinder fitted with a movable piston contains water at 3 MPa, 50% quality, at which point the volume is 20 L. The water now expands to 1.2 MPa as a result of receiving 600 kJ of heat from a large source at 300C. It is claimed that the water does 124 kJ of work during this process. Is this possible?
