Molar concentration

Molar concentration
Common symbols	c, [chemical symbol or formula]
SI unit	mol/m3
Other units	mol/L, M
Derivations from other quantities	c = n/V
Dimension	${\displaystyle {\mathsf {L}}^{-3}{\mathsf {N}}}$

Molar concentration (also called amount-of-substance concentration or molarity) is the number of moles of solute per liter of solution.^[1] Specifically, It is a measure of the concentration of a chemical species, in particular, of a solute in a solution, in terms of amount of substance per unit volume of solution. In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/dm³ (1000 mol/m³) in SI units. Molar concentration is often depicted with square brackets around the substance of interest; for example with the hydronium ion [H₃O⁺] = 4.57 x 10^-9 mol/L.^[2]
