Question

A solution of alcohol in water has been prepared by mixing 150 ml ofalcohol with 600 ml of water. Calculate the volume percentage of the solution.

Answer 1

Percentage concentration=  Volume of solute  x 100%
                                              volume of solution
                   
                                         =   150ml (slovent)     x 100% = 15000
                                               750ml(solution)                     750
                                                                       
                                                    = 20%

%concentration  = 20%
