Molar concentration is a unit of measurement for the concentration of a chemical species, specifically a solute, in a solution, expressed as the amount of substance per unit volume of solution. The most commonly used unit for molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm³ in SI units.
Molarity (M) is the most commonly used unit of solution concentration and is defined as the amount of solute in moles divided by the volume of solution in liters:
M = moles of solute/liters of solution.
A mole is a unit of measurement for a chemical substance, from which the term "molarity" derives.
