Problem 42P

Calculate the concentration of each solution in mass percent.

(a) 132 g KCl in 598 g H20

(b) 22.3 mg KNO3in 2.84 g H2O

(c) 8.72 g C2H6O in 76.1 g H2O

Step-by-Step Solution:
Step 1 of 3

Answer :

           (a) 132 g KCl in 598 g H20

            Mass %= mass of solute /mass of solution*100

                         =132/598*100

                         =22.0

(b) 22.3 mg KNO3 in 2.84 g H2O

Mass %= mass of solute /mass of solution*100

              =22.3/2.84*100

               =0.63

(c) 8.72 g C2H6O in 76.1 g H2O

Mass %= mass of solute /mass of solution*100

              =11.4
