Question

calculate the concentration in terms of mass by volume percentage of the solution containing 2.5 grams Potassium Chloride in 50 ml of potassium chloride solution

Answer 1

Concentration of solution=
Mass of solute/mass of solution x 100

Mass of solute=2.5gm
Mass of solvent=50 gm

2.5/50*100
=2.5x2
=5%
