✒Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

✒The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution

✒Concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.
