Concentration
In
chemistry,
concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration,
molar concentration, number concentration, and volume concentration. The term concentration can be applied to any kind of chemical mixture, but most frequently it refers to solutes and solvents in
solutions. The molar (amount) concentration has variants such as
normal concentration and
osmotic concentration.
