Page 2 - 3. Lesson Note-Properties and Conc. of Solution

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
