That's interesting. From schooldays I knew molarity not but molality (not
being a chemist). However, I suppose that we have to choose names which are
clear to a wide range of people, not just specialists in the field, and I
suspect that the average climate modeller would not be clear about either
molality or molarity. Hence moles_of_X_per_unit mass is preferable, I'd say.
We could use moles_of_X_per_unit volume, which is perfectly clear, but
we already use the word "concentration" to mean something per unit volume,
and I would guess that mole_concentration would be generally understood to
mean mol m-3.

These terms are unusual in having a unit in them (mol). Yes, we could instead
say amount_of_substance_concentration and amount_of_substance_per_unit_mass
since mole is the SI unit of "amount of substance". Is that clearer? I suspect
that it probably is not, to the average user, as it depends on recognising
"amount of substance" as a technical term.

Cheers

Jonathan
