A solution contains x ml of ethyl alcohol mixed with 100 ml of water. The concentration of the solution is 28.6% in terms of volume by volume percentage. Find x.
40 ml
Let the volume of ethyl alcohol (solute) be x ml
Volume of water (solvent) = 100 ml
Total volume of solution = 100 + x
Volume by volume % = volume of solutevolume of solution×100
⟹ X100+X×100 = 28.6
Solving the above equation, we get x = 40 ml
