Water vapor has a low density compared to liquid water because its molecules are in a gaseous state, which means they are widely spaced apart and have greater kinetic energy. In this state, water molecules move freely and occupy a larger volume, resulting in a lower mass per unit volume. Additionally, the intermolecular forces in gases are much weaker than in liquids, allowing the molecules to be more spread out, further contributing to the low density of water vapor.
Temperature: Liquid water is densest at about 4 degrees Celsius. Heat it above or below that and it expands. State: Perhaps a sub-category of temperature, but gaseous water has a much lower density than either ice or liquid water. Pressure: A very small increase in density can be seen by pressurising liquid water, and a very great increase by compressing water vapour. Impurities: The presence of other particles, solvents or living matter in liquid water, ice or vapour has an effect on the sample's density (although this is not really an effect on the water's density by the strictest definition)
Water has a lower density compared to most other liquids because of its unique molecular structure. The hydrogen bonds between water molecules cause them to form an open, hexagonal structure, which spaces the molecules further apart. This arrangement reduces the overall mass of the water, resulting in its low density.
Mercury is used in barometers because it has a high density, does not evaporate easily, and has a low thermal expansion. These properties make it ideal for creating a precise and stable measurement of atmospheric pressure. Water, in contrast, would evaporate easily and change density with temperature, making it less reliable for this purpose.
The molecular mass of water vapour is 18.01528
Because ice is solid and has a heavier weight that cause it to have higher density and as for water vapour, it is gaseous and has lower density due to not having any weight.

Transpiration gives out water vapour which condenses at night because of low temperature.
At high temperature the gas stage of H2O is steam and at low temperature it is water vapour
If the low density water was put over another fluid of lower density it would sink but if it was put over a high density fluid like mercury it would floats.
Saturn has a very low density and it would be able to float on water. The density of Saturn is: 0.687 grams per cubic centimeter.

It's the gas phase of water.
