Answer 1

$\huge\color{blue}{\mathfrak{Hello♥}}$

Normality is defined as the number of equivalents of solute dissolved per liter of solution (equivalents/L = N) (Equations 1, 3, and 4). EW is the equivalent weight in g/equivalent. It is calculated by dividing the molecular weight of solute by the number of equivalents per mole of solute.♥

Answer 2

the normality of the solution gives the number of gram equivalent of the solute present in one litre of the solution.

FORMULA

N = no of gram equivalent of solute/ volume of solution in litre .

no of gram equivalent of solute = mass of solute in gram/ equivalent weight of solute
