Question

what do you mean by concentration of solution

Answer 1

The concentration of a solution is the amount of solute present in a given amount (mass or volume) of solution, or the amount of solute dissolved in a given mass or volume of solvent. Two ways of expressing the concentration of a solution : 
(i) Mass by mass percentage of a solution 
               =    Mass of solute ÷  Mass of solution x 100
 (i) Mass by volume percentage of solution 
               =    Mass of solute ÷ Volume of solution x 100 

Answer 2

The amount of sustance per defined space is called concentration of solution.
