Question

5. The air we breathe is mainly a mixture of nitrogen gas, oxygen gas, and carbon dioxide. What would

the total pressure when the partial pressure of oxygen gas is 0.21 atm, the partial pressure of carbon
dioxide gas is 0.01 atm, and the partial pressure of nitrogen gas is 0.78 atm.

Answer 1

Answer: 160 mm HgTherefore, the partial pressure of oxygen is: PO2 = (760 mm Hg) (0.21) = 160 mm Hg, while for carbon dioxide: PCO2 = (760 mm Hg) (0.0004) = 0.3 mm Hg.
