Psi Kpa Bar
Mole Fraction to PPM conversion??
At a certain point along a pipeline that is carrying a gaseous mixture where the pressure is equal to 150 psi = 8.618 kPa = 0.08618447 bar, and, the temperature is varying in between 35 –> 60 deg C.
In this piepline I have a mole fraction of (H2S) = 0.187.
I need to know the equivalent ppm (Particle Per Million) for the H2S.
Does Avogadro’s theory has to do with this? Or the general gas law PV = nRT??
Please explain your answer in detail 
.187 mole fraction is equivalent to .187 x 6.0623×10^23 number of molecules of the species. Assuming that the total mixture is one mole, ppm would be just 0.187×10^6.
The formula referred by you contains n which is mole fraction of the substance in volume V.
