Question

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

ANSWER:mass of solute=20
mass of solvent=80
mass of solution=20+80=100
concentration=20\100×100=20​

Answer 1

Mass of solute=20g

mass of solvent =80

mass of solution =80+20=100

concentration = 20/100×100

=20%
