P. 2
For example: Suppose a solution is prepared by 20g of sugar in 80g of water,
then
Mass of solution= Mass of solute + Mass of solvent = 20g + 80g= 100g
=
= = 20% mass/mass
Volume- volume percentage: Mass volume percentage is used for the solutions in which
solute is liquid.
Volume- volume percentage can be defined as the volume of solute in mL dissolved for
100 mL of the solution.

For example: Suppose a solution is prepared by dissolving 20mL of sugar in water and
finally making the volume of the solution equal to 200mL.
Volume of solute= 20mL
Volume of solution=200mL
− =
= 20 X100 =10% volume/volume
