Question

A solution contains 5 ml of alcohol in 70 ml of water. Calculate the volume of volume percentage of the solution

Answer 1

Explanation:

Volume percentage is calculated as:

Volume of solvent      x 100%        volume of solvent= 5ml

volume of solution                        volume of solution= 5 + 70 ml = 75ml

%volume= 5ml    x 100      =      20/3  =  6.67%

               75ml   

PLEASE MARK AS BRAINLEST.

Answer 2

Answer:

Volume of volume percentage of the solution is 6.667 %v/v.

Explanation:

Percentage volume by volume,

%v/v = (volume of solute / volume of solution) * 100

• Here, 5ml of alcohol is solute in 70 ml of water and make total 75ml of solution.
• Because solution is solute + solvent which is 75ml.

• So,

            %v/v = (5/75) * 100

                    = 0.0667 * 100

                    = 6.667 %

So, volume of volume percentage of the solution is 6.667 %v/v.
