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. = 5.16E-06 lb/dscf (molecular weight of NO 2 gas = g/g-mole) (ppm) x (molecular weight of NO 2 gas) x (Conv.

I am not aware of anyone expressing Method 25A results as a weight/weight fraction. For ppm on a volume basis, molecular weight is not an issue because a mole of any gas has a volume of 22.4 liters at standard temperature and pressure (STP) regardless of the molecular weight. ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.
