Factor) reference combustor inlet absolute pressure at 101.3 kilopascals ambient pressure, inches of Hg 2014-06-06 One of these is the conversion from a percentage value to a PPM value because 1 PPM is just 10,000 times bigger than one percent. To perform the conversion, then, simply multiply the value in percent by 10,000 or 10 4. For example, if you have a 0.02 percent solution, this is equivalent to 0.02 × 10 4 = 200 PPM, which is a much more convenient fraction, not a weight/weight fraction. I am not aware of anyone expressing Method 25A results as a weight/weight fraction.

Solution : 1.5 percent by volume = 1.5*104 ppm. ppm x molecular weight(g/mol) x 1000 (mg*L/m3*g)  Example – Given a 100 ppm (mole basis) gas mixture of Compound A in nitrogen , For example, if Compound A is hydrogen sulfide, with a molecular weight of  31 Jan 2020 One mole is equivalent to the molecular or atomic mass of the solute. Parts per million, of course, refers to the number of molecules of solute  26 Jan 2021 Calculate mass errors (in ppm) and m/z values based upon molecular formula. Solution: In water, ppm is equivalent to , so we have 5.0 mg/l of TCE. Conversion to molarity units requires only the molecular weight: Often, concentrations below 1  78.0 ppm = 78 mg Ca2+ / L of solution = 0.0780 g/L. 2) Divide by the atomic weight for calcium ion: 0.0780 g/L / 40.08 g/mol = 0.00195 mol/L (to three sig figs)   If the molecular weight is unknown to you, please try our Molecular Weight Calculator.


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.
