What is the range of 1'3'4'1'3'1'5'2'1'1'3'?
calculate range of percentages
What is ninety-five hundredths in percentages?
95%
Write 0.4 as percentages?
40%
How do you calculate the average of 4 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
How do you add percentages together?
same as normal adding!
Why is the amount of gases in the atmosphere usually shown as percentages of dry air?
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.
What are two the most common gasses found in air and what are their percentages?
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
What are the percentages of the top three gas of air?
Air is made up of 78% nitrogen, 20.95% oxygen, 0.93% argon plus traces of other gases.
Why are the amounts or gases in the atmosphere usually shown as percentages of dry air?
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.
What percentages of gases are in the sun's at most?
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:(
Why are the amount gases in the atmosphere usually shown as percentages of dry air?
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.
Why are the amount of gases in the atmosphere usually shown as percentages of dry?
It is simpler because the amount of water vapor in the air can change.
What is the atmosphere of earth?
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.
What are the pasenteges of the gasses in the air?
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.
Why are the amounts of gases in the atmosphere usually shown as percentages 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.
Which gas does the exhaled air contain?
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.
What are the amount of gases in the atmosphere usually shown as a percentage of dry air?
Besides the gases that comprise air, air can also contain variable amounts of water vapor -- characterized by the term, "relative humidity." Because the amount of water vapor held in air can change, it is simpler and more sensible to express component gas percentages on the basis of dry air. Type your answer here...
