Question

80 ml of a solution contains 20 g of solute. What is the concentration of this solution in terms of mass by volume percentage of the solution?

• A. 25

Answer 1

The correct option is A 25
Mass of the solute = 20 g
Volume of the solution = 80 ml
Concentration in terms of mass by volume percentage =
$\frac{\text{mass of solute}}{\text{volume of solution}}\times 100$

= $\frac{\text{20}}{\text{80}}\times 100$

= 25%
