9. Calculate the chemical potential of electrolyte A in an aqueous solution at 298 K and concentration m mol/1000 g H2O. For calculation, use the data of standard thermodynamic properties of ions in aqueous solutions given in the handbook. Calculate the values of the average ionic activity coefficients from the ionic strength of the solution.
N option Electrolyte A m mol/1000g H2O
