Decrease its pressure.
There should be about 0.117 moles of oxygen in the original sample. Is this for the mastering chemistry online quiz? for universiy?

In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
The pressure is 103,5 at.

It is important because capillaries do most of their work of exchanging gases, oxygen and carbon dioxide, by diffusion, which works best under less pressure. ???That is not quite right. Exchange of gases occurs when there are different concentrations in a given sample and it has nothing to do with pressure. Filtration occurs under different pressure, diffusion happens regardless of pressure.
Argon was found in the gaseous state. A sample of clean air was taken. Then oxygen, carbon dioxide, water, and nitrogen were removed. One unknown gas was still in the sample. This was later determined to be Argon.
which sample was removed during surgery and sent to pathologist
A sample of oxygen is a pure gas composed of oxygen molecules (O2), while a sample of water is a liquid composed of hydrogen and oxygen atoms (H2O). These substances have different physical properties and chemical compositions, with oxygen being a gas and water being a liquid at room temperature.
