Answer:

ml , 15 ml and 20 ml of autone is mixed with 50 ml of water . calculate v/v percent of solution in each case

Answer 2

Volume % of solution is calculated as follows:

volume of solute(5ml alcohol in this case)                  x 100%

volume of the solution formed( water plus alcohol= 80 ml)

=      5ml     x 100 %  =  25/ 4    =  6.25%

     80ml

       volume concentration  =  6.25%
