What else can I help you with?
Oxygen composes approximately what percentage of the air you breathe?
Oxygen makes up about 21% of the air we breathe. The majority of the air is composed of nitrogen (about 78%).
What percentage of oxygen can be found in air?
78% Nitrogen 20.5% Oxygen .5% Argon 1% Others for small calculations we take percentage of oxygen in air as 21%
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
The gases in your atmosphere aside from the oxygen and nitrogen make up about what percentage of air?
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
Which is represented in the highest percentage by volume in dry air a oxygen b nitrogen c carbon dioxide d hydrogen?
Nitrogen is the gas that is represented in the highest percentage by volume in dry air, at around 78%. Oxygen follows at about 21%, while carbon dioxide and hydrogen are present in much lower percentages.
What percentage of air we breathe is nitrogen?
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
What gases that comprise the greater percentage of air?
Nitrogen, N2 and oxygen, O2
Is there more nitrogen or more oxygen in dry air?
more nitrogen. percentage of gases in air is as follow 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases
Oxygen composes approximately what percentage of the air you breathe?
Oxygen makes up about 21% of the air we breathe. The majority of the air is composed of nitrogen (about 78%).
What percentage of air is made of nitrogen and oxygen together?
Nitrogen makes up about 78% of Earth's atmosphere, while oxygen makes up about 21%. Therefore, nitrogen and oxygen together make up approximately 99% of the air we breathe.

What is the percentage composition of nitrogen in the air?
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
The gases in your atmosphere aside from the oxygen and nitrogen make up about what percentage of air?
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
What proportion of each gas in air?
