Question

What is the molarity of 10% naoh(w/v) solution?

Answer 1

Molarity of 10%(w/v) of NaOH solution is
no.of moles of solute / volume of solution.
i.e 10/40 = 1/4 i.e 0.25M.
I hope it will help u...

Answer 2

10% solution of NaOH means 100ml of solution contains 10 gm of NaOH

Molarity of 10%(w/v) of NaOH solution:

Number of moles of solute divided by volume of solution.

 10/40 = 1/4 =$0.25M$

Ans : 0.25 M is the molarity of 10% NaOH solution.
