Your question is not worded very well, but this answer is directed at what I think you are trying to ask.
Water (chemical structure: H2O) has 2 Hydrogen atoms and 1 oxygen atom. If you add the atomic masses of each of these, you get (1.01+1.01+16.00=) 18.02 Atomic Mass units (amu).
Oxygen gas (O2) has 2 oxygen atoms combined and weighs 32.00 amu.
Nitrogen gas (N2) has 2 Nitrogen atoms and weighs (14.01+14.01=) 28.02 amu.
The reason why water seems to weigh more than these is because it is a liquid and is more dense. You can fit many more molecules of water into a space than you can of oxygen or nitrogen at normal room temperature and pressure. Because of this, the same volume of water will weigh more than a volume of air (Oxygen or Nitrogen)- it has many more molecules in the same volume.
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
the answer is atmosphere and trosphere
No; oxygen, nitrogen, and water are all separate elements.
The element's symbols are N and O, the gaseous diatomic molecules are represented by N2 and O2 .
Water molecules have the molecular formula of H2O. This means that it is made up of hydrogen and oxygen atoms. Water molecules are V-shaped and very small.
humid air is lighter that an equal volume of dry air at the same temperature.
nitrogen & oxygen. 75% nitrogen & 2 sumthing % oxygen.
Yes, they do have molecules. In fact everything is made up of molecules even gases like oxygen, carbon dioxide, nitrogen ect.

in pure water, no. Water is comprised of two hydrogen molecules and one oxygen molecule
the answer is atmosphere and trosphere
The five components of the atmosphere include nitrogen, oxygen, carbon dioxide, water vapors and other gaseous molecules. Nitrogen and oxygen make up most of the atmosphere.
No; oxygen, nitrogen, and water are all separate elements.
Nitrogen, yes. Water, no. Water is a compound of the elements oxygen and hydrogen.
The main components of the atmosphere are: Nitrogen (approximately 78%) Oxygen (approximately 21%) Argon (approximately 0.93%) Carbon Dioxide (approximately 0.038%) Along with other gases of a much smaller proportion.
Warm, moist, humid, air associated with a low pressure system is actually lighter than dry air - owing to the fact that hydrogen molecules in water vapor (H20) are lighter than Oxygen or Nitrogen molecules. This moist air rises - causing air pressure to be relatively low compared to surrounding air.
