Question

80ml of solution contains 20g of solute. calculate the concentration of solution in terms of mass by volume percentage of the solution

Answer 1

Volume of solution is 80 ml

Mass of solute is 20ml

Solution =mass / volume *100

=20/80*100

=25%

Answer 2

20% is the concentration of the solution in terms of mass by volume percentage of the solution.

Explanation:

Given,

Amount of solvent = 80ml

Amount of solute = 20g

so,

Mass of the solution = 80 + 20

= 100

∵ The concentration of solution in terms of mass by volume percentage of the solution = Mass of solute/Mass of solution * 100

= 20/100 * 100

= 20%

Thus, 20% is the correct answer.
