Abstract
This review provides historical background on the terms mole, mole per liter, and molar as it discusses their status with respect to the SI system of measurement. Currently the prevalent use of mole per liter and molar does not conform with the recommendations which apply to SI units in general. The article suggests an approach for dealing with this problem in teaching.
