What else can I help you with?
If air is 20.9 percent oxygen by volume what is the volume of air that contains 225 ml of oxygen?
Divide 225ml by 20.9, then multiply by 100.
Is nitrox an oxidizer?
Yes, nitrox is an oxidizer. It contains a higher percentage of oxygen than normal air, which can increase the risk of oxygen toxicity if not used properly. Nitrox is commonly used in scuba diving to extend bottom time and reduce the risk of decompression sickness.
What percentage of oxygen is in inspired air?
About 21% of inspired air is oxygen.
What proportion of each gas in air?
The percentage of oxygen in air is 21%.
What is the difference between burning steel wool in air and burning it in a pure oxygen?
burns faster in pure oxygen as the percentage of oxygen is less in air
What percentage of the air around is pure oxygen?
Air contains about 19-20% oxygen
What is the percentage difference between inhaled and exhaled oxygen?
The percentage difference between inhaled and exhaled oxygen is around 5-10%. When we inhale, we breathe in air that contains approximately 21% oxygen, and when we exhale, the air we breathe out contains around 16-17% oxygen due to the exchange of gases that occurs in the lungs.
What percentage of dry air is made up of carbon dioxide?
its air dry made up of oxygen...

What percentage of oxygen is in inspired air?
About 21% of inspired air is oxygen.
What is the maximum oxygen percentage at air?
Room air is about 21% oxygen.
What the oxygen percentade composition in air?
oxygen percentage in air is 20%
How much oxygen does exhaled air contains approximately?
A small percent . exhaled air always contains oxygen .
Why air dissolved in water contains maximum percent of oxygen?
Air dissolved in water contains a higher percentage of oxygen than nitrogen because oxygen is more soluble in water than nitrogen. This is due to the differences in their molecular characteristics, such as molecular weight and polarity, which affect their solubility in water.
What is the approximate oxygen content in human exhaled air?
Human exhaled air typically contains around 16% oxygen content. This percentage is lower than inhaled air due to the body's utilization of oxygen for metabolism and the subsequent release of carbon dioxide during respiration.
How many times greater is the percentage of oxygen than the percentage of carbon dioxid?
By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.There is 523.75 times as much oxygen in air as there is carbon dioxide.
