Question

A solution of potassium chloride in water is 35% (m/v) The density
of the solution is 1 2 g/ml calculate the concentration of the
solution in % (m/m)

Geetha · Accepted Answer

Mass /Vol % of KCl = 35 %That means mass of KCl = 35 gVolume of solution = 100 mlMass of solution = Volume × density = 100 ×1
2 = 120 gMass / mass % = Mass of solutemass of solution  × 100 = 35120× 100 =29
17 %
