The best way to explain this is by doing some examples: Problem #1: Convert 78 ppm of Ca2+ ions to mol/L Solution: 1) By the last definition of ppm just above: 78 ppm = … #molefractionMole Fraction Mass Fraction and Ppmsign up at http://www.sidza.com and enjoy free video lectureslive 1 on 1 class (Free demo lesson) http:// Basically, ppm is already micromoles per mole. To turn moles of gas into a volume, you need to know the number of molecules of gas in a set volume at a given temperature and pressure, and use the 2017-05-11 This means that there is 25,000 PPM in 2.5 percent. Use the same procedure when you want to convert new values in percent to get the corresponding results in parts-per-million. The Percent to PPM converter gives quick and accurate results based on the values you enter in the blank text field. How to convert percent to ppm. 1%VOL = 10,000 ppm 1 % H2S (Hydrogen Sulfide) = 10000 ppm H2S. So. Example: find how many ppm are in 1.7%. x (ppm) = 10000 ⋅ 1.7% = 17000 ppm.
