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.
20 Αυγ 2021 · Gas concentration from ppm to mg/m³ and vice versa. This online calculator converts the gas concentration value from ppm to mass concentration and back taking into account temperature and pressure.
To convert from ppm to mg/Nm3 we work with the top and bottom parts of the above formula separately. We start by converting the 200 moles of SO2 to milligrams (mg), and then we convert the 1 000 000 moles of total gas mixture to normal cubic meters (Nm3).
Begin: Step: Part per million ↔ Milligram/100grams Conversion Table. 1 ppm =. 0.1 mg/100g. 2 ppm =. 0.2 mg/100g. 3 ppm =. 0.3 mg/100g. 4 ppm =.
Convert PPM to mg/m3: We need to cover the PPM to mg/m3 for gasses, it can be easy to convert the PPM to mg/m3 by the parts per million calculator. The formula for the conversion: concentration (mg/m3) = 0.0409 x concentration (ppm) x molecular weight. Example: Convert 100 ppm of NH3 into the mg/m3: Sol: Now the molecular weight of NH3=17.03 g/mol
mg/m3 = 0.0409 X Concentration (ppm) X Molecular weight (g/mol) An example of this would be, if our display shows we have 50 ppm of Ammonia at standard conditions we would use above calculation to convert ppm into mg/m 3 .
How do I convert mg/m3 to ppm at different temperatures and pressures? The number 24.45 in the equations above is the volume (liters) of a mole (gram molecular weight) of a gas or vapour when the pressure is at 1 atmosphere (760 torr or 760 mm Hg) and at 25°C.
