13. For a two-component liquid solution of water (1st component) - acetone (2nd component) at T = 298 K, p = 1 atm, the dependence of the molar volume of the solution v on the mole fraction of the second component N2 is known.
Necessary:
1) construct a graphical dependence of the molar volume of the solution on the mole fraction of the second component
2) determine the partial molar volumes of both components with a mole fraction of the second component equal to 0.2.
3) calculate the molar mass of the solution and the mass density of the solution at this mole fraction.
