Solute concentration units in mass transport

Dear all,

I would like to know what units I should use to enter a solute mass flux (I am simulating a solute injection).

I have the value in kg/s. Do I have to convert it to mol/s ? Any solute concentration should be entered in moles in OGS?

Thank you very much.


There is now a webpage on some basic conventions like units of BCs and STs: OGS Conventions
