The earth's atmosphere at sea level.
Is ordinary air about 21 percent oxygen and 78 percent nitrogen?
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 - Matthew Pote

What two elements comprise 99 percent of the volume of the Earth's atmosphere?
Earth's atmosphere is roughly 78% Nitrogen & 21% Oxygen.
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.
