Calculate the concentration (in percentage by weight) of a solution obtained by mixing300 g 25%by weight solution ofNH4Cl and150 g of 40% by weight solution ofNH4Cl.

Answer:
30.00
Solution:

Weight of solutionI and II = 300 + 150 = 450 g 
Weight ofNH4ClinI solution=25×300100= 75 g
Weight ofNH4ClinII solution=40×150100=60 g
     Total weight ofNH4Cl = 75 + 60 = 135 g
     % by wt. of mixed solution =135450× 100 = 30%
