A solution contains 30ml of ethyl alcohol mixed with 100ml of water. What is the concentration of the solution in terms of volume by volume percentage?
Volume of solute (ethyl alcohol) = 30ml
Volume of solvent (water) =100ml
Total volume of solution=30 + 100 = 130ml
Volume by volume % = volume of solutevolume of solution×100 = 30130×100 = 23.07%
