Question

Calculate the molarity of a solution prepared by dissolving 4g of Sodium hydroxide in one litre?

Answer 1

hope this helps u.molarity=no.of moles of solute/volume of solution inL

Answer 2

HLO MATE HERE IS UR ANSWER.

GIVEN THAT

W= 4 G

Mw = 23+16+1 = 40 g

V = 1Lrs /1000ml.

FORMULA .

M = w/mw × 1/ v( inltrs) (or) M= w/mw × 1000/v(in ml)

M = 4/40 × 1000/1000

= 0.1M
