Question

what is the percentage of carbon dioxide in air (kalkata)​

Answer 1

Answer:

0.04%

CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed.

Answer 2

Answer:

Oxygen occupies almost 21% of the total gases in the atmosphere. Argon, carbon dioxide and many other gases in total forms the remaining 1%. Carbon occupies about 0.03% of the earth's atmosphere. In the pre-industrial time, the level of carbon dioxide was only about 280 parts per million.
