THE SOLUBILITY OF GASES IN LIQUIDS - NIST
The Mole Ratio, N The mole ratio, N, is defined by N = n(g)!n(l) Table 1 contains a presentation of the most commonly used inter-conversions not already discussed. For gas solubilities greater than about 0.01 mole fraciton at a partial pressure of 1 atmosphere there are several additional factors which must

Hydrogen Sulfide in Aqueous Solvents
srdata.nist.govHydrogen sulfide exists, in aqueous solution, in equilibrium with its ions. Solubilities which have been compiled correspond to bulk solubilities. For this purpose the number of moles of hydrogen sulfide in solution has been taken to be the sum of the number of moles of the uncharged H2S plus those of HS- and those of S--.
