What gas is represented in the highest percentage by volume in dry air?
The element Nitrogen has by far the highest % composition of dry air. It is also the highest percentage by volume in wet air. Only the percentage is known (78.09%), because it is impossible to measure the total volume of air as it is constantly changing.
Why are the amounts of gases in the atmosphere usually shown as percentage Of dry air?
The amount of water vapor in the air changes significantly with location and temperature. so a listing of percentage of gasses in the atmosphere would be different depending on how much water was in the air sampled. That would not be useful, because the other gases in the atmosphere do not change all that much. So it is more helpful to describe the making of the atmosphere as dry air (containing no moisture) and then adjust if needed for the humidity at any one place and time.
