Nearly 100% of air is gas. The rest is particulate matter: dust, pollen, and also tiny organisms.
40%
95%
calculate range of percentages
Add them together and divide by 4 (the number of percentages you had in the first place) It's just like averaging plain numbers

Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Air is made up of 78% nitrogen, 20.95% oxygen, 0.93% argon plus traces of other gases.
i don't know the percentages but i do know that hydrogen and helium are the 2 main gases! sorry this did not completely answer the question:(
Showing the amounts of gases in the atmosphere as percentages of dry air allows for easier comparison and understanding of their relative concentrations. It provides a standardized framework that eliminates the variability that water vapor would introduce, making it simpler to analyze and compare the composition of the atmosphere.
Showing gas concentrations as percentages of dry air allows for easier comparison of the relative amounts of different gases in the atmosphere. Dry air is a consistent reference point because its composition is relatively stable, making it a convenient baseline for expressing variations in gas concentrations.
Gases in the atmosphere are measured in percentages to provide a clear and standardized way of expressing their concentration relative to the total volume of air. This percentage format makes it easier to compare the abundance of different gases, such as oxygen, nitrogen, and carbon dioxide, and to understand their roles in processes like respiration and climate change. Additionally, using percentages helps scientists and researchers communicate findings effectively across various disciplines.
It is simpler because the amount of water vapor in the air can change.
The atmosphere of the earth is the layers of air that surround the Earth. They contain nitrogen, oxygen, carbon dioxide, water vapor, and small percentages of other gases.
The composition of gases in air is approximately 78% nitrogen, 21% oxygen, 0.9% argon, and trace amounts of other gases such as carbon dioxide, neon, helium, and methane. These percentages can vary slightly depending on factors like location and elevation.
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.
Exhaled air will contain all of the gases in regular air, except that it will have higher percentages of carbon dioxide and lower percentages of oxygen. (It still will have oxygen, or CPR wouldn't work.) It will also have water vapor from our lungs. The main gas in inhaled and exhaled air is nitrogen. This is followed by oxygen, then carbon dioxide, then other gases. Yes, there is still more oxygen exhaled than carbon dioxide, but at a smaller percentage than was inhaled. Chances are that your teacher is looking for the gas, carbon dioxide, as your answer, since that is the product of cellular respiration that is disposed of in exhaled air, but it isn't the main component of exhaled air.
