Question

calculate the norma
nality and molarity of 5% of Nao H
solution?​

Answer 1

5% solution means 5 grams of NaOH is present in 100 ml of solution

weight of solute = 5gms

volume of solute =100 'll

molarity=weight of solute/G.M.W ×1000/100

M=5/40×1000/100

=1.25M

normality=w/G.E.W ×1/V

N=5/40×1000/100

=1.25N
