Question

For 50 ml of 60% acetone how much water is needed

Answer 1

Percent volume of miscible liquids is calculated using the following formula:

% volume = volume of solute / volume of solution × 100%

 The solute in this case is the acetone ( as it is being dissolved in the water)

Volume of solute = 5ml

The volume of the solution is given by the combined volume of the acetone and water = 50 ml

Therefore the % volume = 

 5ml / 50ml × 100% = 5 × 2 = 10%

Therefore the volume % of the acetone = 10%
Therefore
Given :

Volume of Solute =5ml
Volume of Solution=50ml

Volume By Volume Percentage = [Volume of Solute/ Volume of solution] x 100

=[5/50]x100

=[1/10]x100

=10%

∴Volume percentage of solution is 10%
