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 of oxygen at sea level?(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?
