Three of the primary components of air are carbon dioxide, nitrogen, and oxygen. In a sample containing a mixture of only these gases at exactly one atmosphere pressure, the partial pressures of carbon dioxide and ni- trogen are given as PCO2 = 0.285 torr and PN2 = 593.297 torr. What is the partial pres- sure of oxygen?
Answer in units of torr
Ptotal = pO2 + pCO2 + pN2
Ptotal must be in torr if the others are in torr. 1 atm = 760 torr.
