What are the SI units for molarity?

Well, that's sort of a trick question. The SI has decided that "molarity" is obsolete, and they prefer the term "amount-of-substance concentration" (yeah, it's stupid). Those units are mol/m^3.

However, the unit for molarity as it's used in chemistry and biology is the molar (M), or moles per liter (mol/L).
