where (VMW) is the molar volume of the methanol/water associate.

Now, the weight of the water in the solvent mixture (wW) will be given by,

(14)

Similarly, the weight of the methanol in the solvent mixture (wM) will be

(15)

and, finally, the weight of the methanol/water associate in the solvent mixture (wMW) will be
