In this case the conversion of ppm to mg/m 3 depends on the molecular weight of the contaminant. For example, 1 ppm chlorine represents one part of chlorine in one million parts of air by weight, which is 1.45 mg/m 3. The ppm unit is mainly used in North America. Source: GreenFacts

*Please select more than one item to compare where; MW = molecular weight, PPM = parts per million, vol = volume in liters of one mole of gas. You can then correct the volume to actual process conditions and as such carry through the correction to your concentration conversion. Number average molecular weight (M n) determination. In 1H NMR spectroscopy, the area under each resonance signal is proportional to the molar concentration of the protons being analyzed. Number average molecular weight (M n) determination by end-group analysis using 1H NMR therefore involves identifying and integrating The chemical formula for N,N-dimethylaniline is C8H11N, and its molecular weight is 121.18 g/mol. (5,7) N,N-Dimethylaniline occurs as a yellow oily liquid that is insoluble in water. (1,3,5,7) The odor threshold for N,N-dimethylaniline is 0.013 parts per million (ppm).

Concentration = (ppm * Molecular Weight) / (10 6 * Volume @ T, P) 1.6% by volume = 1.6 * 10 4 ppm. Molecular Weight of CO = 28 g/mol. Volume of 1 mol of CO at 0 º C (T) & 1 atm (P) = 22.4 * 10-3 m ³( STANDARD) Volume of 1 mol of CO at 25 º C (T) & 1 atm (P) can be calculated as follows ( Apply P1V1T2 = P2V2T1 ) =22.4*(273+25)/(273+0) = 24.5

Ppm molecular weight

In the input field of Molecular Weight you could either choose from the drop-down list, or you ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg. One ppm is equal to 1/1000000 of the whole: 1ppm = 1/1000000 = 0.000001 = 1×10-6 . One ppm is equal to 0.0001%: 1ppm = 0.0001%. ppmw X ppm = (Y mg/m 3) (24.45)/ (molecular weight) CONVERT MG/M 3 TO PPM. Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ 1) Unless specified otherwise, ppm usually refers to ppm by weight: 2.89 ppm = 2.89 g per 1,000,000 g (or any other weight unit, I have just chosen g for convenience) 2) Now you need to know the density of the solvent to convert the volume to mass.
