Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
Oxygen is the most common gas in the air we breathe, followed by nitrogen as the second most common gas. Nitrogen makes up about 78% of Earth's atmosphere.
Oxygen is the second most common gas found in the air we breathe.It has composition of 21% by mass and comes after nitogen which is 78%.
Air contain nitrogen (78 %), oxygen (21 %), argon (1 %) and other minor constituents.
