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

Is that a liquid or is that a solution in water? If a solution, you need to know it's strength.
In general, for a liquid, you need yo know its density, then you can calculate how many grams you have. Then divide by the molecular weight to get moles.
If a solution, you need to know how much is substance and how much is solvent. You need some statement of strength of solution and whether that statement (especially percent or ppm) is by weight volume, mole fraction, etc.
