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 $1.01 \times 10^5 \textrm{ N/m}^2$. (a) What is the partial pressure of oxygen at sea level? (b) If the diver breathes a gas mixture at a pressure of $2.00 \times 10^6 \textrm{ N/m}^2$, what percent oxygen should it be to have the same oxygen partial pressure as at sea level?
1. $2.11 \times 10^4 \textrm{ N/m}^2$
2. $1.06 \%$
