Answer 1

Answer #1

If you want to achieve an oxygen concentration of 80% by blending air and O₂ together, then to achieve this you have an air: O2 ratio of 2:3

Explanation - Air has an oxygen percentage of 21% (approx 20%)

Then providing the mixture of 40% air and 60% oxygen will give a total 80% of oxygen concentration in that mixed air.

Suppose you want to climb a mountain that is 19,000 feet tall. The air at that altitude has a total pressure of about half an atmosphere. The chemical composition of the air is the same as at sea level. Suppose you want to breathe the same partial pressure of oxygen that you normally would breathe at sea level – no more and no less. You decide to breathe bottled air from a tank, and adjust the composition of the air...
