it contains 78% nitrogen 21% oxygen and 1% Argon in clean air. However There are more chemicals in that 1 remaining percent such as Helium, Carbon Dioxide, Methane, etc. But the Majority of that 1% is Argon therefore we class the 1% as Argon

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
Where would you find 79 percent nitrogen 16 percent oxygen 4.5 percent carbon dioxide?
In the air around you.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
Percent by volume. Nitrogen is almost insoluble in blood at normal pressures. Oxygen is replaced by carbon dioxide so % nitrogen stays the same.
What is over 99 percent of the atmosphere in pure dry air composed of?
Nitrogen 78%, oxygen 21%
What is the composition of nitrogen and oxygen in boiled off air and water with the ordinary air?
nitrogen-65% and oxygen-30 to 34%
The air you breathe is made of 21 percent oxygen and 78 percent nitrogen The oxygen in air is the?
It's the oxygen. Since oxygen doesn't dissolve into nitrogen - air is a mixture, not a solution - you can't call it the solute and the nitrogen the solvent, which may have been the answer you thought you were going to get.
Why is oxygen 21 percent and nitrogen 78 percent?
This is the composition of the air.
What is air made out of?
air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon
What is the percentage composition of nitrogen in the air?
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Which three gases make up over 99.9 percent of the air?
The three gases that make up over 99.9 percent of the air are nitrogen (about 78 percent), oxygen (about 21 percent), and argon (about 0.9 percent).
Which gas-in-air is the most-abundant?
Nitrogen, you can't survive on it obviously but you breath it in every day it is the most abundant gas in the atmosphere followed by oxygen I think.
What gas has a percent of volume of 20.95?
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
Which two gases make 99 percent of the air?
Nitrogen and Oxygen.
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?

Where would you find 79 percent nitrogen 16 percent oxygen 4.5 percent carbon dioxide?
In the air around you.
Do you take in 1 percent of air when you breathe?
Ous air consists of 71% nitrogen and 29% oxygen.
