EX/ A sample of argon (molar mass 39.9 gmol) of mass 6.56 g occupies 18.5 dm' at 305 K. (a) Calculate the work done when the gas expands isothermally against a constant external pressure of 7.7 kPa until its volume has increased by 2.5 dm. (b) Calculate the work that would be done if the same expansion occurred reversibly.
