Water contained in a piston-cylinder assembly, with initially quality of 0.25(25

Question

Water contained in a piston-cylinder assembly, with initially quality of 0.25(25%), is heated until the piston hits the stops. Heating continues until the pressure is 3bar. The mass of the piston is 40kg, and its diameter is 10cm. The atmospheric pressure is 100kPa. the initial and final positions of the piston are shown in pic. Find
1.The initial pressure and 2.the mass of water 3. the quality when the piston hits the stops and the 4. Final temperature along with 5. the work and heat transfer for each process and last 6. the force exerted on the stops at the final state and then sketch a p-v and T-b diagrams showing states and the process.
