Default transport-consumption problem

Hi everybody! I'm describing a transport-consumption problem of a gas dissolved in a solvent (the mixture is very dilute -gas mass fraction is 6.856145*10-06 -, with no bubbles formation). What would the best approach be to model it? Should I activate species transport and define a mixture composed by the solvent and the gas? And in defining the mixture density should I apply "volume-weighted-mixing-law"? Actually mixture density is the same as solvent one. And with regard to gas consumption on the walls, what about defining the walls as velocity_inlet with "negative velocity = gas consumption rate" and "gas mass fraction = 1"? Thanks
