Molality (m) is defined as the number of moles of solute per kilogram of solvent.
Molality =moles of solute/kilograms of solvent.
Molarity tells how many moles of substance you have per unit volume of solvent(moles/v).
Normality;isn't 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.
