We do not know exactly why but we can surmise that Jupiter has a rather large rocky core and also, being so large, some of the hydrogen it is made form could be in a dense, metallic state near the core
Saturn's atmosphere appears to have half the helium content of Jupiter because Saturn has a lower overall density than Jupiter, leading to a greater proportion of hydrogen compared to helium in its atmosphere. Jupiter's higher density means that there is more helium present in its atmosphere compared to Saturn.
Terrestrial Planets are more dense than Jovian planets because terrestrial planets are mainly made of solids such as rock and metal, whilst Jovian planets are mainly made of gasses, and the density of solids is much higher than that of gases

Saturn and Jupiter are less dense than water. Saturn's density is about 0.69 g/cm^3, while Jupiter's density is about 1.33 g/cm^3, making them less dense than water, which has a density of 1 g/cm^3.
Jupiter has greater mass than Saturn. Jupiter is the most massive planet in our solar system, with a mass more than 300 times that of Earth, while Saturn is the second most massive planet, with a mass about 95 times that of Earth.
No, Saturn is not the gassiest planet in our solar system. Jupiter holds that title as it is predominantly composed of gases like hydrogen and helium. Saturn is also a gas giant planet but has a lower density than Jupiter.
Saturn isn't denser than Earth. Saturn is about one eighth the density of Earth. It is less dense because it is mostly composed of hydrogen and helium while Earth is made mostly of rock and iron.
The gravitational pull from Jupiter to the sun is stronger than the gravitational pull from Saturn to the sun. This is because Jupiter is more massive than Saturn, so it exerts a greater gravitational force over larger distances.
On a larger planet, such as Jupiter or Saturn.
Much less than that of Earth. For example, Saturn's density is less than that of water; Jupiter's density is slightly larger than that of water.
Saturn is smaller than Jupiter primarily due to differences in their formation and the amount of material available in the protoplanetary disk from which they formed. Jupiter, being the largest planet in the solar system, had a more substantial gravitational pull that allowed it to accumulate more gas and dust. Additionally, while both planets are gas giants, Jupiter's larger mass has contributed to its greater density and size compared to Saturn, which has a lower overall density. This difference in mass and composition is a result of their unique evolutionary paths in the early solar system.
Four planets, Jupiter, Saturn, Uranus, and Neptune, have mass greater than that of the Earth.
