Answer 2

$\huge\textbf{Normality :}$

Normality can be defined as the number of grams equivalents present in 1 litre of solution.

$Normality$ = $\frac{Number\:of\:gram\:Equivalent}{Volume\:of\:solution}$

$Number of grams early$ = $\frac{Given\:mass}{Equivalent\:mass}$

= $\frac{w}{equivalent\:weight}$

$Equivalent weight$ = $\frac{Molar\:mass}{Valency}$

= $\frac{m}{valency}$

$N$ = $Valency$ × $\frac{w}{m}$ × $\frac{1000}{volume}$

$\textbf{N}$ = ${Valency\:×\:M}$

===================================

$\huge\textbf{Molarity :}$

Can be defined as number of moles of solute present in 1 kg of solvent.

$m$ = $\frac{Number\:of\:moles\:of\:solute}{Mass\:of\:solvent}$

$\textbf{m}$ = $\frac{w}{m}$ × $\frac{1000}{mass}$
