Pentane is 0.626 g/cm^3 at 25 C and one atmosphere. Hydrogen is 0.070 g/cm^3 at -253 C and one atmosphere. -- Uncle Al http://www.mazepath.com/uncleal/
kerosene
The floating liquid will have a lower density than the liquid it is floating on.

i think gasoline
The liquid with the lowest density will float on top of liquids with higher densities. This is because objects with lower density are less dense than objects with higher density, so they will sit on top of them.
Liquid mercury
I suppose that this liquid is the liquefied atomic hydrogen at 20 K: 0,07099 g/cm3.
But you have not presented us with any list.
The layer with the highest density will be found at the bottom of the beaker. This is because denser liquids sink while less dense liquids rise.

The density generally decreases as a substance transitions from solid to liquid to gas. In the solid state, particles are tightly packed resulting in higher density. When the substance melts into a liquid, the particles become less ordered and the density decreases. As the liquid is further heated to form a gas, the particles are further apart, leading to the lowest density.
