American Heritage® Dictionary of the English Language, Fourth Edition
- adj. Of or designating a solution that contains one mole of solute in 1,000 grams of solvent.
Century Dictionary and Cyclopedia
- Of, or pertaining to, that amount of an element or compound which is equal to its molecular weight taken in grams. This amount is sometimes called a mol, and from the term in the German language an adjective molar is derived. The use of this German form of the adjective in English is infelicitous, since the English word ‘molar’ has already a very different meaning. Accordingly, some have lately used the adjective molal.
GNU Webster's 1913
- adj. (Chem.) Being at a concentration with the designated number of moles (of solute) per 1000 grams of solvent. Compare molar.
- adj. designating a solution containing one mole of solute per kilogram of solvent
