By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
Answered. In Biology. The atmosphere is about 20% oxygen, about 79% nitrogen, about 1% Argon, and a fraction of a per cent of a number of other gases, including 400 ppm (parts per million) of carbo â¦ n dioxide. One per cent is 10,000 ppm, so 400 ppm is less then 1%. It is 0.04%.
