A solution contains 40 ml of ethylalcohol mixed with 100 ml of water. What is the concentration of the solution in terms of volume by volume percentage.

Text Solution

Verified by Experts

Volume of solute = 40 ml
Volume of solvent = 100 ml
Total volume of the solution = 40 + 100 = 140 ml
Volume of vol. percentage = volume of sulute x 100/volume of solution
`rArr" "v//v% = 40 xx 100//140 = 28.57%`
