    G/dm3 shows the mass per volume of solution.

    Mol/dm3 shows the number of moles per volume of solution

    grams, g, is the SI unit for mass. mol are the SI unit for amount of substance.

    A concentration can be expressed as the mass of a substance per unit volume, which is g/dm3 or by number of moles per unit volume, mol/dm3 or M.

    Do you know the difference between mass and amount of substance, and how mol/dm3 and g/dm3 are totally different things?
