There is a very simple relationship between normality and molarity:

$N = n\:\times\: M (where\:n\:is\:an\:integer)$

For an acid solution, n is the number of H

provided by a formula unit of acid.

   Example:

A 3 M H2SO4 solution is the same as a 6 N H2SO4 solution.

For a basic solution,

n is the number of OH- provided by a formula unit of base.

 Example:

A 1 M Ca(OH)2 solution is the same as a 2N Ca(OH)2 solution.

Normality is a moles of H+ or OH- divided by liters of solvent.

So if you had one mole something like H2SO4

there would be 2 moles H+ per mole H2SO4

so normality would be double Molarity.

Same thing with Ba(OH)2.

Normality would be triple Molarity in H3PO4.

$Molarity = moles\:of\:solute/liters\:of\:solution$

$Molality = moles\:of\:solute/kilograms\:of\:solvent$

$Normality = number\:of\:mole\:equivalents\:1 L\:of solution$
