A mixture of helium and oxygen is commercially known as heliox and generally refers to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available.

The percentage of oxygen in diving varies depending on the diving depth and the type of diving. For recreational diving, the typical oxygen concentration is around 21%. However, for technical diving, the oxygen concentration can be increased up to 100% to reduce the risk of nitrogen narcosis at greater depths. Helium is often used as a diluent gas in technical diving to reduce the amount of nitrogen in breathing mixtures at very deep depths. The percentage of helium varies typically between 0% and 90% depending on the dive plan and depth.

What is the mixture 15ml of oxygen and 5ml of helium?
A mixture of oxygen and helium is used in diving.
Is oxygen gas also known for helium?
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
How much helium is in a helium tank?
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
What percentage is present in air?
78 percentage of nitrogen.21 percentage of oxygen.1 percentage of other gases. Example-argon,carbon dioxide,helium,neon & methane. -superman
What percentage of Uranus is water?
There is no Oxygen on Uranus. Uranus is primarily composed of Hydrogen and Helium

Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
What are marine applications for helium?
As breathing gas for diving: A mixture of oxygen and helium (some times containing nitrogen or a small percentage of oxygen) is used to avoid the phenomenon of narcosis when only pure oxygen is used; also helium make the effort for breathing easier.
How much helium is in a helium tank?
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
Is helium poisenous?
No however the lack of oxygen is deadly. It is unlikely that you will hurt yourself sucking the helium out of balloons, as long as you breathe oxygen in between breaths of helium. There is a small percentage of helium (.0005%) in the earths atmosphere.
Which gases weigh more than air Im aware that helium qualifies but also you are aware that you have few known sources of this gas IE What other gasses are a viable choice for diving?
- Helium is less dense than air. - For diving, as diluents for oxygen nitrogen and helium are used.
What is the concentration of helium on Jupiter?
The concentration, in the atmosphere, is about 10%.
Does helium dissolve into oxygen?
yes, helium does dissolve into oxygen.
Is helium oxygen?
No. Helium and oxygen are two different elements.
How deep can a person dive with helium-oxygen air tanks?
It depends on the percentage of the mixture You can adjust the percentage depending on desired depth and length of dive.
What percentage is present in air?
78 percentage of nitrogen.21 percentage of oxygen.1 percentage of other gases. Example-argon,carbon dioxide,helium,neon & methane. -superman
What percentage of Uranus is water?
There is no Oxygen on Uranus. Uranus is primarily composed of Hydrogen and Helium
