I need help please!

A mass of 1 kilograms of carbon dioxide (CO2) in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 3 MPa, T1 = 204°C:

Process 1–2: Constant-temperature expansion until the volume is twice the initial volume.

Process 2–3: Constant-volume heating until the pressure is again 3 MPa.

Assuming ideal gas behavior, determine the overall work, in kJ.
