How to calculate a molar volume of a solution?
« on: January 10, 2007, 07:05:50 AM »
Hallo. I have a solution of 4 known compounds, I'm given the molar volume of each compound and molar fraction of each compound in the solution. How can I calculate a molar volume of the whole solution. Thank you.

You have the molar fractions and the molar volumes of each compound which can give you the volume that each compound has in the mixture.

It's the same principle as Dalton's law of partial pressures.

If we denote M as molar volume, then
M1 + M2 + M3 + M4 = Mtotal

where 1, 2, 3, and 4 are the molar fractions.
