In what scenario....?

Explanation:

Atmospheric pressure, #1*atm#, is the sum of the individual partial pressures...

#1*atm=760*mm*Hg=sum(P_(N_2)+P_(O_2)+P_"other gases")#

This is another restatement of old #"Dalton's Law of partial Pressures"#....

For the air we breathe now, #P_(O_2)=160*mm*Hg#...and #P_(N_2)=500*mm*Hg# to a first approx...

For the relation between partial pressure and mole fraction, see here.
