The density of a planet depends basically on the density of the materials that make the planet up. It is a weighted average of those densities.
No. Terrestrial planets are much denser than Jovian planets.
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.

Well, some planets, such as Mercury, have little density. For example, the amount of density in oil compared to water. That scenario is an example of the amount of density that you might expect on such planets as Venus.
No. Terrestrial planets are much denser than Jovian planets.
Inner planets
All of them. Anything with mass has density.
The Terrestrial planets have a higher density. Their structure includes a large percentage of rock, while the Jovian planets are composed mostly of gas.

Jovian planets are more massive and lower in average density. Terrestrial planets are smaller and higher in average density.
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.
Sir Isac Newton was the scientist who discovered why the planets stay in orbit.
