Examples. • How many µmol are dissolved in 2 l of a 20 mM solution? 20 mM 13-5 First convert concentration from ppm in M or mol/L. 4.48 ppm = 4.48 =1.80 ×10.

[1] parts per million is equal to mg/liter. If you know the molar mass of the substance, then you know the number of moles. Example, if you have 50 ppm, that is 50 mg/liter. If the molar mass of the stuff is, say, 100 gm/mole that is the same as 100 mg/mmole. THen you have 50 mg/liter or 50/100 = 0.5 mmole/liter = 0.5 mM. The concentration C in parts-per million (ppm) is equal to the concentration C in milligrams per kilogram (mg/kg) and equal to 1000000 times the molar concentration (molarity) c in moles per liter (mol/L), times the solute molar mass in grams per mole (g/mol), divided by the solution density ρ in kilograms per cubic meter (kg/m 3): ppm = 1mg /L millimolar = millimol /l There is no direct conversion between these two , It varies with the compound dissolved: Take NaCl : Molar mass 58.5g/mol 1ppm NaCl = 1mg/L NaCl = 0.001g/58.5g/mol *1000mM/M = 0.017millimolar.
