Molarity tells how many moles of substance you have per unit volume of solvent (moles / V)
Molality, basically the same as above, excepts its moles per mass of solvent (moles / m(solvent))
Normality is not so straight forward, as it have different meanings depending on what you are dealing with:
In acid-base chemistry, normality is used to express the concentration of protons (H+) or hydroxide ions (OH−) in a solution.
In redox reactions, the equivalence factor describes the number of electrons that an oxidizing/reducing agent can accept/donate.
In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction.
