Concentration and
Molarity
The amount of solute (solid) dissolved in a solvent is
referred to as its concentration.
The concentration of a solution expresses the amount of
solute (gram or moles) dissolved
in a unit volume (usually liter or dm3) solution.
(By
contrast, solubility expresses the
quantity of solute per unit volume or a specific mass of the solvent.)
–For example, 10.1 g of
NaCl dissolved in distilled water and made to a volume of 1.00
dm3 (or liter) gives us a NaCl solution of
concentration 10.1 g/dm3.
