There should definitely be some indication here that a mole fraction is a measure of moles as an "amount" rather than weight. — Preceding unsigned comment added by 124.169.164.82 ( talk) 11:08, 15 April 2012 (UTC)
Who's Calls this 'Amount Fraction'...Someone pls show me or give me and explanation of any higher education society that uses the term amount fraction over mole fraction...This is a specific ration of MOLES of a substance. —Preceding

I'm a bit confused here. The article appears to me to be a long-winded way of giving a dictionary definition, that the "mole fraction" of a component ("type of molecule") in a mixture is the proportion of molecules in the mixture to belong to it.
Is that correct? If so, can't we say so?
Appealing to moles appears to me to be a bit of a detour - for non-chemists, who are going to use this for theoretical rather than practical purposes, molecules are a more immediate concept. The mole fraction of X in Y is the probability that a molecule of Y, chosen at random, is actually X. The rest is pretty much obvious.

Can anybody tell me if you take the moles of the solute before or after it has been dissolved? Electrolytes like e.g. NaCl form ions when they dissolve. -- 173.53.83.10 ( talk) 21:29, 12 February 2010 (UTC)

Non-uniform spatial values of mole/mass fraction causes diffusion, so the qualifier (spatially) non-uniform mixture is better phrasing than inhomogeneous mixture which refers to multi-phase mixture(s).-- MagnInd ( talk) 10:05, 17 July 2012 (UTC)
As far as I can remember Mole wasn't so wide and complex definition. It is simple number of molecules. That is all. Whoever wrote this article, wrote article about reasons for inventing mole in first place, but not mole itself. Marek Artur Penther 86.150.164.79 ( talk) 06:04, 11 May 2014 (UTC)
Is Mol% commonly used? I just saw it in an article on plutonium in bombs. As well as I know, it is more usual to use mMol when Mol is too big. I would change that one to mMol, but I thought I should ask here first. Gah4 ( talk) 15:18, 9 February 2017 (UTC)
