20 cm3 of acetone is added into the water of volume 230 mL. The percentage by volume of acetone in the solution is:
The correct option is B 8% As we know, 1 cm3=1 mLVolume of solute =20 mLVolume of solution =250 mL%V/V=20/250×100=8%
A solution contains y ml of acetone in 150ml of solution. The concentration of the solution is 25% in terms of volume by volume percentage. Find y.
