Normality=0.125molL1.

Explanation:

Here molarity normality. Why? Because hydroxide anion does not speciate to any degree in aqueous solution.

And molarity moles of solutevolume of solution

=5g40.0gmol11L=0.125mol1L=0.125molL1 with respect to NaOH(aq).

What is pH of this solution? We know that pH+pOH=14 under standard conditions.
