Normality in Chemistry:
Normality of a solution is the number of gm-eqv. of the solute present in 1 litre of the solution. Thus,
Normality = wt. in gms of solute per litre of the solution / eqv. wt. of the solute
or, Normality x eqv. wt. of the solute = wt. in gms of solute per litre of the solution.
Molarity in Chemistry:
Molarity of a solution is the number of moles of the solute present in 1 litre of the solution. Thus,
Molarity = wt. in gms of solute per litre of the solution / Mol. wt. of the solute
or, Molarity x Mol. wt. of the solute = wt. in gms of solute per litre of the solution.
