Can someone please answer this question for me I am really confused

Question

Oil and water do not mix with each other. But when we add oil into water, oil floats over

the water. What property of oil makes the oil float on water?

Answer 1

The oil floats on top of the water because the oil is less dense than the water. Since oil and water do not mix the oil floats on top of the water rather than the other way around.
