The earth has an overall density of 5.5 g/#cm^3# similar to other "rocky" worlds in the inner solar system. Saturn has a density of 0.7 g/#cm^3#. If there was an ocean of water somewhere big enough to hold Saturn, what would happen?

Saturn would float.

Explanation:

Less dense substances float on more dense substances. An ocean contains sea water, which contains dissolved salts and other solutes. The average density of sea water is #"1.027 g/cm"^3"#, so the less dense Saturn would float on the sea water.

Saturn would also float on fresh water, which has a density of #"1.0 g/cm"^3"#.
