None of the planets in our solar system except Earth are thought to have surface liquid water in any considerable amount. Some planets are known to have water ice or atmospheric water vapor; some moons of Saturn and Jupiter (which are not planets) show evidence of having sub-surface oceans of liquid water owing to tidal heating effects; other planets including Mars and Venus (both of which were thought to have significant amounts of surface water in their history) continue to be studied for the possibility of liquid water below the surface.
Earth is unique in having liquid water at its surface.
Yes, of course. Think about it: just about all bodies of liquid water on the planet -- technically "liquid solutions" -- are a home to many species of fish that breathe the oxygen -- a gas -- that is dissolved in the water.
Ceres is a dwarf planet, not a planet. It is believed to have a substantial amount of ice, but not liquid water.

The question seems poorly worded, but Earth is the planet with liquid water on its surface.
Earth is the only known planet to have oceans of liquid water.
water doesnt really contain density, but depending on its state (solid, gas, etc) it has a density. to get the density you would take the mass and divide it by the volume. usually, liquid water has a density of 1 kg/L

Google says that earth has 70% water on the planet but there is no planet with water on it completely.
Earth is the only known planet with liquid water.
Earth is the main planet with liquid water. There are some studies which say that Neptune and Uranus also contain water, deep inside them. However, only the Earth has liquid surface water.
Ceres is a dwarf planet, not a planet. It is believed to have a substantial amount of ice, but not liquid water.
