- NexSens Technology Inc. For dilute solutions, one part per million equals one mg/L. In most cases, the two are considered equal. To convert from molarity to ppm, first determine the molar mass of a substance.

1 ppm = 0.001 mg/ml. 1 x 0.001 mg/ml = 0.001 Milligrams Per Milliliter. ppm↔ml/l 1 ml/l = 1000 ppm. ppm↔ul/m3 1 ppm = 1000 ul/m3. ppm↔ug/mg 1 ug/mg = 1000 ppm.

PPM stands for Parts Per Million, it is a chemical term used to represent a very low concentration of a solution. Milliliter and Liter are units to represent volume of liquids.

Multiply times The molecular weight and divide by 1000. The mass in mg that corresponds to 1 mol (1 millimol) depends on the compound. On the label of commercial container of any chemical there is a number that is the molecular weight (MW) or form

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 1 ppm in ICP-read out is 1 mg Cu/L 1/63.5=mmol/L, 63.5 molecular weight of Cu you need a dilution factor if the analyte is a solid. For example 10 g soil: 60 mL extracting solution the DF will be 6 Massa och molmassa.
