Dear 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 FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

ppm implies a mixture, parts of one thing in millions of parts of a second thing. You haven't told us what the second thing is, liter of water, cubic meter of air, etc.

To convert the moles of the first thing, we need to know what it is, or at least its molecular weight. We also need to know whether the ppm should be stated on mass ratio, mole ratio, volume ratio, etc.
