Q5 of 25 Page 154

Find the concentration of the solution in terms of weight percent if 20g of common salt is dissolved in 50g of water.

Concentration in weight percent can be found as:



•Where the weight of solution= weight of the solute + weight of solvent


•The weight of solute (common salt) = 20g


•The weight of solvent (water)= 50g


•Weight of solution= 20g+50g= 70g
