Sea water is a mixture of salts and water which cannot be separated except by evaporation. Therefore, sea water is considered homogeneous.
Sea water also contains mud, decayed plant, etc., other than salts and water, so it is heterogeneous also.

Given:
One mole of an ideal gas undergoes isothermal irreversible expansion against constant pressure 5 atm at 300k from 50m3 to 550m3.
To find:
Work done in kJ/mole
Calculation:
The general expression for work done in reversible isothermal expansion :
Putting values in SI units :
So , work done is -5.98 kJ/mol.
