Question

Calculate the normality of solution of NaOH, if 0.4 g of NaOH is dissolved in 100
ml of the solution.
​

Answer 1

Answer:

1 N

Explanation:

molar mass of NaOH is 40.

0.4 gm NaOH = 0.1 mole NaOH

100 ml solution contains 0.1 mole NaOH

then 1000 ml solution contains 1 mole NaOH

molarity = 1 M

n factor of NaOH is 1

normality = molarity * n factor = 1 N
