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.
The atmosphere.

air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
nitrogen about 75 (probably 65-85%)

air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon

The atmosphere.
The air we breathe is mostly made up of nitrogen and oxygen. The remaining 1% is made up of argon, carbon dioxide and other trace gases. Even water vapor (water in its gaseous state) is present in air in varying amounts.
I think mostly oxygen, and some nitrogen. Also, some carbon dioxide.
78% nitrogen gas 21% oxygen gas
nitrogen is 78% while CO2 is part of a percent
It is normally know as 'air' and air is made up mostly of nitrogen and oxygen. Oxygen is the gas that the body needs to survive.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
The 4 elements are Nitrogen, Oxygen, Carbon and Hydrogen.
