Percentage solution and Mass fraction (chemistry) seem to deal with basically the same topic, and both are way too short to justify forking. A merge perhaps? Mikael Häggström ( talk) 15:24, 21 March 2011 (UTC)
In general, merging two very short and similar articles makes sense. However, I see a problem here: "Mass fraction" is a well-defined quantity (see IUPAC definition), whereas "percentage solution" seems to be some imprecise term apparently used by biologists. I fear that merging the articles will only increase confusion. I make an alternative suggestion: Convert "percentage solution" into a disambiguation page with 3 entries:

Claiming that the terms "weight percent" or "weight-weight percent" are obsolete ignores the fact that they are quite widely used in industry to refer to mass fraction. While I understand encouraging using true IUPAC nomenclature, the "obsolescence" of these terms should not be mis-represented — Preceding unsigned comment added by Ohenn ( talk • contribs) 22:17, 10 February 2012 (UTC)
Note that mass percentage (also called mass percent) is not the same as mass fraction. They differ by a factor of 100, see "Related quantities".
Regarding the improper name percent concentration, to add to the confusion, take a look at percentage solution.-- RolfSander ( talk) 07:54, 30 August 2012 (UTC)
50% = 0.5 So the symbol % just means "divided by 100", as shown in the [ article here].— Preceding unsigned comment added by Humanlike2015 ( talk • contribs) 15:02, 3 April 2018 (UTC)
The mixing of two pure components can be expressed introducing the (mass) mixing ratio of them . Then the mass fractions of the components will be:
The realtion gets rather interesting or non-trivial starting with ternary mixtures.-- 82.137.8.113 ( talk) 00:13, 12 August 2016 (UTC)
The redirect w/w redirects to this article, and Percentage solution says to come to this article for an explanation of "% w/w". But I find no explanation of what is meant by these expressions in this article. Does "% w/w" mean the same thing as "wt%"? Is there an explanation somewhere else on Wikipedia? Should an explanation be added to this article?
For example, if a saline solution has a salt content of 20% w/w, is that 20% salt mass per unit of mixed saline solution mass or 20% salt mass per unit of water mass? Assuming it is the former, I just edited the article to say it.
