mol%min and mol.ppm max
Thread Content
Dear sea friends, what are the units for mol.% min, mol. ppm max, and wt.ppm max, and what do they mean?
mol % = Mole percentage = Percentage of molecules = Percentage of gas volume; ppm = Part per million; wt = Weight
First of all, since this is an ideal gas, the molar percentage is the same concept as the volume percentage； Converting it to a percentage of mass: First, the average molecular weight is necessary to know ； Secondly, it is necessary to know the molecular weight of the component being analyzed ； Third, to convert volume ppm to mass ppm, divide the volume values in the numerator and denominator by 22.4 and then multiply by their respective molecular weights.
