Question

The solubility of potassium Chloride at 20 degree C is 34 7 g in
100 gm of water The density of the solution is 1 3 g/ml What is the
w/V % of potassium chloride in the solution? Please give the
explanation

Dear Student,
Total mass of solution = mass of KCl + mass of water
= (34 7 + 100)g = 134 7g
Volume of solution = mass of solution Ã· density
of solution
= 134 7 Ã· 1 3 = 103 62 ml
So, w/ V% of KCl = (mass of KCl Ã· volume of
solution) Ã— 100
= (34 7 Ã· 103 62) Ã— 100
=33 49% (w/V)
Hope! This explanation helps you
