M = PPM/ mm / 1000. Where M is the molarity; mm is the molar mass (g/mol) PPM is the parts ; PPM to Molarity Conversion. The conversion of PPM to molarity involves using the molar mass along with the equation above to calculate molarity. PPM to Molarity Example Example 2 - Converting CAC Releases from ppm (mass) to tonnes. If you have had your stack tested for total particulate matter (TPM), PM 10 or PM 2.5 you will notice that the results from the laboratory are usually in the units of parts per million mass or ppm (mass). PPB to PPM Converter. This is a conversion calculator that is used to convert the numbers in parts-per-billion (PPB) to parts-per-million (PPM).

The ppm and ppb are discussed in terms of mass/volume quantities. 15.03: Solution Concentration - Molality, Mass Percent, ppm and ppb Last updated; Save as PDF Page ID 178209; No headers. A similar unit of concentration is molality (m), which is defined as the number of moles of solute per kilogram of solvent, not per liter of solution: 2011-04-05 · To convert from ppm by volume to ppm by mass, multiply by the density of the particles. For mineral grains (clay, silt and sand sizes), this will typically be 2.65 g/cm3. For example, a sample with a volume concentration of 25 µl/l will have a mass concentration of 25*2.65 = 66 mg/l. To convert from ppm by mass to ppm by volume, divide by the PPM is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms.
