what are the units for concentration in chemistry
Molar concentration (also called molarity, amount concentration or substance concentration) 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 litre, having the unit symbol mol / L. A solution with a concentration of 1 mol / L is said to be 1 molar, commonly designated as 1 M.
