Answer to Question #21913 in Inorganic Chemistry for austin

Question

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 = 629.702 torr. What is the partial pressure of oxygen?

Answer 1

The formula to calculate the partial pressure of oxygen:P(O2) = Pcommon - PCO2 - PN2
1atm = 760 torr
Partial pressure of oxygen:
P(O2) = 760 torr -0.285 torr - 629.702 torr =130.013 torr
Answer:
Partial pressure of oxygen=130.013 torr
