For instance, chloride has a molar mass of 35.5. A solution with 1 M concentration would have 35.5 g of chloride per 1 L of solution. Molecular weight of substance = 28 Molar volume = 22.4 litres (In this example the molecule is CO) 2.1 To convert concentrations in ppm to mg/m3 Concentration of substance = 120 ppm Molecular weight of substance = 28 Molar volume = 22.4 litres Concentration in mg/m3 = concentration (ppm) x molecular weight of substance molar volume = 120 ppm x 28 parts per million is abbreviated as ppm 1 ppm is one part by weight, or volume, of solute in 1 million parts by weight, or volume, of solution. In weight/volume (w/v) terms, 1 ppm = 1g m-3 = 1 mg L-1 = 1 μg mL-1; In weight/weight (w/w) terms, 1 ppm = 1 mg kg-1 = 1 μg g-1; Please do not block ads on this website. MW = molecular weight in grams per gram-mole (g/g-mole) NO x Conc. = 46 NO x Conc.

Assuming that your 1:10 mix is calculated in weight, the 2020-03-31 Molecular weight of substance = 28 Molar volume = 22.4 litres (In this example the molecule is CO) 2.1 To convert concentrations in ppm to mg/m3 Concentration of substance = 120 ppm Molecular weight of substance = 28 Molar volume = 22.4 litres Concentration in mg/m3 = concentration (ppm) x molecular weight of substance molar volume = 120 ppm x 28 Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc.. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution.ppm is defined as. ppm = 1,000,000 c / s = 10 6 c / s (1). where . c = molar mass, volume or mass of component (mole, m 3, ft 3, kg, lb m) MW = molecular weight in grams per gram-mole (g/g-mole) NO x Conc. = 46 NO x Conc. = 5.16E-06 lb/dscf (molecular weight of NO 2 gas = g/g-mole) (ppm) x (molecular weight of NO 2 gas) x (Conv.
