At STP (Standard Temperature and Pressure: 1 atmosphere of pressure, 0oC), one mole of any gas will occupy 22.4 liters of space. One mole of any substance contains 6.02 x 1023 particles (similar to how a dozen is 12 of anything). Air is about 21% oxygen, depending upon your location and local biotic and abiotic factors.
So, at STP, 1 liter of air is about 0.21 liters of oxygen. To find out how many moles that represents, divide 0.21 by 22.4. Take that answer and multiply by 6.02 x 1023. It should be a very large number, on the order of 1021.

∙ 6y agoThere is no such thing as an "air molecule." Air is a mixture of different types of molecule, mostly nitrogen and oxygen. One oxygen molecule contains two oxygen atoms.

Who "People breathe in oxygen molecules from the air and exhale carbon dioxide molecules. Because of this, the air is full of carbon dioxide and oxygen mixed together. What is this an example of"?
Increase in entropy
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
humid air is lighter that an equal volume of dry air at the same temperature.
What are 3 gases in the air which are molecules?
Nitrogen, oxygen (including ozone), carbon dioxide
Why do you have low oxygen when you go high on the mountains?
Because the higher you go, the less air molecules there are.
Air is about 78.0 percent nitrogen molecules and 21.0 percent oxygen molecules Several other gases make up the remaining 1 percent of air moleculesWhat is the partial pressure of nitrogen in air at at?
0.780 Atm
How many out of 200 air molecules are oxygen?
Air is 21% oxygen so 21% of 200 is 42 oxygen molecules.
How many milliliters of nitrogen and oxygen are present in one liter of dry air?
20.95%oxygen and 78.08% nitrogen

How do you get oxygen to a space station?
They have oxygen generators with catalysts that change the chemical structure of the air molecules that pass through them , converting carbon molecules into oxygen ; that's how the get oxygen to a space station...
What do people breathe?
Air: 78% nitrogen, 21% oxygen, 1% other. We breathe oxygen and other molecules.
How does the distance between the particles in atmospheric air compare to the size of the particles themselves?
Usually in a gas, the distance between molecules is larger.
How does the iss get air?
They get air from a generator that splits water molecules into hydrogen and oxygen!! :) Hope it helped!!
