Question

A solution contains 5 ml of alcohol dissolved in 0.2 L of water. Calculate the concentration of the solution in terms of volume percentage.
PLZ HELP.........

Answer 1

Mass of solute = 20 g

Volume of solution = 500 ml

Mass by volume percentage =

Volume of solution

Mass of solute×100

=

500

20×100

=4%

Answer 2

Answer:

Solution :

Concentration of solution = Volume of solute

Volume of solution×100

Volume of alcohol = 5 mL

Volume of solution = (5 + 75) = 80 mL

Concentration of solution = (5mL)(80mL)×100

=6.25%
