Q. 0.2gm of NaOH is dissolved in one litre of water . Determine its molarity.

Answer 1

Hey Prakash!
Here's your answer.

Mass of NaOH=0.2 g
Moles of NaOH =
$\frac{mass}{molar \: mass}$
Thus moles=0.2/40=0.05

Molarity =
$\frac{no. \: of \: moles \: of \: solute}{volume \: of \: solution \: in \: litres}$
Thus
Molarity =0.05/1=0.05

Hey Prakash!

Here's your answer.

Mass of NaOH=0.2 g

Moles of NaOH =

Thus moles=0.2/40=0.05

Molarity =

Thus

Molarity =0.05/1=0.05
