Expert Answer
Strength: The strength of a solution is defined as the amount of a solute in grams present in one litre of the solution, and hence is expressed in g/litre and is usually written as g L-1.
Strength = Mass of the solute in grams / Volume of the solution in litres
Normality: Normality of a solution is defined as the nuber of gram equivalent of the solute dissolved per litre of given solution. It is expressed by "N".
N = Number of gram equivalent of solute / Volume of the solution in litres.
N = Strength in grams per litre / Eq. mass of solute
Ex. If eq. mass of sulphuric acid is 49 then, a solution of sulphuric acid having 0.49 gram of it dissolved in 350 ml of solution will have its normality as follows:
N = (0.49 g / 49 g eq-1) x ( 1000 cm3L-1/350cm3) = 0.03 g eq L-1
