The following liquids don't mix with water. Which of these liquids would float on top of water?

(I) benzene, C₆H₆, d = 0.877 g/cm³
(II) carbon disulfide, CS₂, d = 1.263 g/cm³
(III) chloroform, CHCl₃, d = 1.483 g/cm³
(IV) ether, (C₂H₅) ₂O, d = 0.714 g/cm³
(V) gasoline, d = 0.675 g/cm³

Liquids that float on top of water have a density less than that of water (1.0 g/cm³). Benzene (I), ether (IV), and gasoline (V) have densities of 0.877 g/cm³, 0.714 g/cm³, and 0.675 g/cm³, respectively, which are all less than the density of water, indicating they would float.
