ppm is an abbreviation of parts per million. ppm is used to measure very low concentrations. In this page, you will know how to calculate ppm and how to convert from ppm to %.
How does one convert from ppm (vol or weight) to moles or g/l etc in a LIQUID ? Upvote 0 Downvote Apr 21, 2004 #8 25362 Chemical Jan 5, 2003 4,826 For liquid solutions, whenever the concentration in volume units must be changed to mass units, or the reverse, density must be...
You cannot follow the RDA with this product or you will likely be taking much more than your body needs.X ppm = (Y mg/m3)(24.45)/(molecular weight) Y mg/m3 = (X ppm)(molecular weight)/24.451mg

Soluble chromates leach from the conversion coating areas adjacent to the scratch and precipitate on the open metal surface, thereby providing a self-healing of the defect (Kendig et al., 1993). Chromate treatments produce effective paint bonds through molecular adhesions with the film being bound...
Unaveraged solid-state 13C NMR resonance of the CH carbons in the norbornene (53 and 49 ppm) evidenced the conformation conversion from T[X]T and G[X]G to more stable T[X]G conformers (where [X] = [T] or [G] represent the norbornene chain conformation). As the persistent length ...
To prevent this, it is advisable to choose a raw material that is free of unsaturation or to eliminate it using complementary techniques such as epoxidation [9]. Figure 1 displays the various stages of biomass production, from cultivation to extraction of the compounds of interest, as well as...

2a). Ethene dominates at lower temperatures due to the MPV reaction, while C₃₊ hydrocarbons become prominent at higher temperatures due to the HP mechanism. Finally, surface acetate species (183 ppm in the ¹³C NMR spectrum), formed from acetaldehyde oxidation, are observed. While ...
