I am trying to run React and it's asking for the molar volume of H2S (g). Does anybody know where Ican get that kind of information.

Specific volume of H2S(g) is 0.699 m3/kg, according to

http://www.airliquide.com/en/business/prod...ex.asp?GasID=59. Recalculated to molar volume it is about 23823,248 cm3 per 1 mole of H2S. However, I don't know how to input the molar volume into GWB, since editing dataset doesn't seem to work in this case. Actually, molar volumes of gases depend significantly on temperature - it's not good to constrain gases in volume units. My advice is: use fugacity to constrain H2S(g) in your initial system. If H2S(g) is a reactant in your model, constraining in units other than cm3 should work (e.g. gram, mol, ...)
