Question

what is the reason for kerosene floating in water​

As kerosene has more refractive index than water, it is optically denser. The mass density of kerosene is less than water, so kerosene drops will float in water, when both are mixed.

Hope it helps you out

Answer 2

The reason for kerosene floating in water is that kerosene's density is lighter than water density.
