Calculate the electricity energy required in units of D for desalinating 150 w of water and it takes 3.70 kWh/m^3 of water?

At 25°C temperature and 1 bar pressure, one mole of gas is heated to 300°C in a piston-cylinder mechanism and pressurized to 10 bar pressure. Calculate the heat and work information required for this process for both methods below: Method A. Isothermal compression to 10 bar followed by isobaric process heating to 300°C. Method B. The PV will be compressed to constant, followed by isobaric process cooling or heating to 300°C if necessary. The gas can be assumed to be ideal (Cp = 38 J/(mol K). Solve correctly please
