Concentration terms of Solutions

Hello everyone,

Today i am going to explain some concentration terms of Solutions.

1.) Mass % 

Mass of solute present in 100gm pf solution.

               W/W% =  Weight of solute / Weight of solution × 100

2.) Volume % 

Volume pf solute present in 100ml of solution.

              V/V % = Volume of solute / Volume of solution × 100

3.) W/V % 

Mass of solute present in 100ml of solution.

            W/V % = Weight of solute / Volume of solution ×100

4.) Mole fraction :

It is the ratio of number of moles of that component of which mole fraction is to be determined to the number of moles of all components.

                 

 5.) Molarity (M) :

Number of moles of solute present in one litre of solution.

                                    M = moles of solute / volume of solution

6.) Molality (m) : 

Number of moles of solute present in one kg of solvent.

                                    m = moles of solute / weight of solvent

         

7.) Normality (N) : 

Number of gram equivalent present in one litre of solution.

                               N = W × 1000/ E × Volume of solutions

                   Or,.      N = molarity × n.f.
