Three liters of saturated liquid R-134a at a constant pressure of 200 kPa is contained in an insulated piston-cylinder device. Inside the cylinder, an electric resistance heater is turned on and 900 kJ of energy is transferred to the steam. Determine the change of entropy of the refrigerant during this process in kJ/kgK (with three significant figures).

can you make it more obvious. i can't see it properly
