Explanation:

Concentration is a measure of the amount of solute in an amount of solvent or solution.

These are some units used to express the concentration, depending on the measure (concept) used:

Measure             Definition                                               units

(concept)

Molarity              moles of solute per liter of solution      mol / liter

Molality              moles of solute per kg of solvent          mol / Kg

% (w/w)               percent mass/mass                                 % g / g

% (w/V)                percent  mass / volume                          % g/V

% (V/V)                percent volume / volume                        & V/V
