The molar volume for a mixture of methanol (1) + water (2) at 298.15 K and 1 bar is given as

D. Let’s assume you have an equimolar mixture of water and methanol. What will be the molar vol ume of this mixture according to the functional form given in the problem? What will be the molar volume of this mixture if you assumed this mixture behaved as an ideal solution?
