What is Noramality, Molarity and Molality?

There are simple easy step to calculate Normality, Molarity and Molality.

It is easily explained in below video. Many of us don’t have clear knowledge about it,

And we find difficulties during real practice in lab and interview. So without wasting your more time let’s start learning…

Normality, Molarity & Molality are the units of concentration. All three units express amount of solute dissolves in solvent.

First we will learn Molarity

So when 1 gm mole solute dissolved in 1000 ml solution it’s called

1 molar or 1 M solution. Symbol for Molarity is “M” so we can say that Molarity is amount of solute in mole dissolved in 1 liter solution.

Be clear that final volume of solution must be 1 liter.
