RE: Pondering solubility He in water or brine17 Aug 2021 04:58
1 milliMole of He = 4gms/1000
One gram in 1000 ml is 1000 ppm
0. 004gms = 4ppm
Th chart on the link agrees with my low ppm in water solubility.
I think DM has it all wrong. That's a geolgist doing chemistry, or they found 2 to 4 ppm of He N Karroo, which would be the normal range (up to 20ppm) as free He gas, which you could find in Rotherham, let alone Rukwa..
If it's the latter, move on elsewhere. If it's wrong and he's measured 2%, then it has to be free gas and he should STFU about it.
