2. The dependence of the saturated vapor pressure of magnesium over a Mg-Cu solution on the composition at 1000 C is shown in the table.
Mass. % Mg 100 85 55 34 16 10
рMg*10-2, Pa 15.00 13.81 11.06 5.75 1.119 0.40
Determine the activity and activity coefficients of Mg in solution, the nature of the deviation from Raoult’s law and plot the dependence of Mg activity on the mole fraction of Mg.
