Answered step-by-step
The composition of atmospheric air is primarily made up of the following gases, measured by their mole fractions:
- Nitrogen (N₂): Approximately 78.08%
- Oxygen (O₂): Approximately 20.95%
- Argon (Ar): Approximately 0.93%
- Carbon Dioxide (CO₂): Approximately 0.04%
Additionally, air contains variable amounts of water vapor, which can range from about 0% to 3% depending on humidity levels, as well as trace amounts of other gases such as neon, helium, methane, and krypton
