Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of amount of substance per unit volume.
It is important to distinguish the unit of mass (moles) from the unit of concentration (molarity). Moles are simply a unit of mass and are abbreviated as mol. Molarity is designated by an upper case âMâ and is defined as moles per liter.
