Question

A solution contains 80 gram of potassium chloride in 300 gram of water. Calculate the concentration in terms of mass by mass percentage of the solution.

Answer 1

Answer: Hey! I dont`t have the exact answer but this example might help you-

Mas  of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

              =360 g

concentration of solution=
