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.
What else can I help you with?
What happens when water vapor is lighter than nitrogen or oxygen?
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.
What is the chemical formula for nitrogen and oxygen?
The element's symbols are N and O, the gaseous diatomic molecules are represented by N2 and O2 .
Does oxygen and nitrogen contain water?
No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
Which two gasses make up most of earths atmosphere?
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.
What is the difference between dry air and wet air?
the answer is atmosphere and trosphere
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
Water vapor molecules rise in the atmosphere, causing them to form clouds and ultimately precipitation. This is because lighter molecules have more kinetic energy and therefore move faster, allowing them to rise above the heavier nitrogen and oxygen molecules.
What happens when water vapor is lighter than nitrogen or oxygen?
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.
What are the two ions found in water molecules called?
nitrogen & oxygen. 75% nitrogen & 2 sumthing % oxygen.
Does nitrogen oxygen neon carbon dioxide water or methane have molecules?
All of the substances listed (nitrogen, oxygen, neon, carbon dioxide, water, methane) have molecules. Molecules are formed when atoms of the same or different elements bond together through chemical bonds. Each of these substances is made up of molecules that give them their unique properties and characteristics.
What is the chemical formula for nitrogen and oxygen?
The element's symbols are N and O, the gaseous diatomic molecules are represented by N2 and O2 .
What are the five components of the atmosphere?
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.
Is water a compound formed by sharing nitrogen?
No, water is a compound formed by sharing oxygen atoms, not nitrogen. Water (H2O) is composed of two hydrogen atoms and one oxygen atom, with the oxygen atom sharing electrons with the hydrogen atoms to form covalent bonds.
Which of these is a compound water nitrogen oxygen or hydrogen?
Water is a compound made of hydrogen and oxygen. Nitrogen and oxygen are elements on their own.
Does oxygen and nitrogen contain water?
No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
Why is oxygen not soluble?
Oxygen is actually soluble in water to some extent, but it is not as soluble as other gases such as carbon dioxide or nitrogen. The low solubility of oxygen in water is due to its nonpolar nature and the weak interaction between oxygen molecules and water molecules.
Are nitrogen and water elements?
Nitrogen, yes. Water, no. Water is a compound of the elements oxygen and hydrogen.
Which two gasses make up most of earths atmosphere?
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.
