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 in a given volume. A commonly used unit for molar concentration used in chemistry is mol / L.
Molarity tells how many moles of substance you have per unit volume of solvent (moles / V) Molality, basically the same as above, excepts its moles per mass of solvent (moles / m(solvent)) Normality is not so straight forward, as it have different meanings depending on what you are dealing with: 1  In acid-base chemistry, normality is used to express the concentration of protons (H+) or hydroxide ions (OHâ) in a solution.
