Question

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

Answer 1

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   

Answer 2

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    

therefore answer is 6.67%
