whats the equation for converting ppm to mol/L?
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

What kind of "parts?" Parts per million can be a ratio of two quanitites measured in moles, volume, or weight, and in general, the three ppm values will be different. If you don't know what KIND of ppm you have, there is nowhere to start.
If you do know, then write the ppm as umol/mol, ug/g, or uL/L Now you can see what conversions you must perform on the numerator and denominator to get what you want. You will probably need to know the density and/or molecular weight of both the substance and the solvent. This means knowing their names and chemical formulas to consult chemical references.
In general, an equation would only apply to a particular substance, solvent, and type of ppm. You really need a process.
