Saturn is less dense...Water is 1000 kg/m^3 and Saturn is 700 kg/m^3
Earth is more than 5 times denser than water. Of all the planets in the solar system, only Saturn is less dense than water.
The density of something is how much material there is in a given space. It is sort of like "thickness". A very dense material will be heavy even in small amounts. Water, for example, is denser than air. This is why it is more difficult to move through water than it is through air. Air particles are spaced further apart from each other than water particles. A solid, such as stone, is denser than water, so dense that is impossible to move through. Saturn's average density is less than that of water. This is because Saturn is mostly gas.
The matter from Saturn must be less dense than water, which is why it floats, while the matter from Earth is denser than water, causing it to sink. This suggests that the matter from Saturn likely has a composition that differs from the matter found on Earth.
The question sounds as if you expect Saturn to have a surface like Earth, part of which has oceans. Let's get this clear: the giant planets - including Saturn have no surface. Instead, they are gas giants - the gas just gets denser and denser, the lower you go. Saturn will, of course, have some water vapor, water droplets and water ice in its atmosphere. Part of its rings consist of water ice as well.

This question is not clear.
No. It is less dense. That's why it floats above water.
Kerosene is less dense than water.
This depends on the density of this item: more denser than water-sink, less denser than water-float.
An object that is denser than water will sink when immersed, while an object that is less dense will float. This is because objects with higher density displace less water and therefore sink, while objects with lower density displace more water and float.
Saturn has a density less than water, so it would float if there was a large enough container of water to hold it. Saturn is made mostly of hydrogen and helium, which are less dense than water.
Wrong, nitrogen is less dense than water!
