There’s a number ways to express concentration and one way is molarity. Other ways to express concentration are parts per million. When you hear about pollution or things like that, you’ll hear PPM of lead or whatever is in the air. The FW of an ion species is equal to its concentration in ppm at 10-3 M. Fluoride has a FW of 19, hence a 10-3 M concentration is equal to 19ppm, 1M is equal to 19,000 ppm and 1ppm is equal to 5.2 x 10-5 M. Go here for ISE molarity/ppm conversions shown in Table III. PPM to Molarity Convert ppm to gram based or milligram based concentration. Normality / Molarity = Molar Mass / Equivalent.

Just by entering the value of PPM in g/L and its atomic weight in g/mol, you will get the resultant value of molarity in mol/L. Molarity is a measure of number of molecules per unit volume, and ppm (parts per million) is a measure of proportion by mass. If the solution is dilute enough that adding the solute does not appreciably change the solution's volume or mass, you can perform this conversion. 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): Parts per million also known as PPM is a used for measuring the substance quantity per million parts of solution. Our online molarity to PPM calculator will help you to convert more than 100 different types of elements from molarity to ppm considering the atomic mass of the typical element.
