Question

A deep sea diver should breathe a gas mixture that has the same oxygen partial pressure as at sea level, where dry air contains 20.9% oxygen and has a total pressure of 1.01 ✕ 10⁵ N/m².

(a)

What is the partial pressure (in N/m²) of oxygen at sea level?

N/m²

(b)

If the diver breathes a gas mixture at a pressure of 2.00 ✕ 10⁶ N/m², what percent oxygen should it be to have the same oxygen partial pressure as at sea level?
