Question #60dd4 Chemistry Gases Partial Pressure 1 Answer Nathan L. Jun 5, 2017 #132# #"mm Hg"# Explanation: We can take note of the fact that air is roughly #21%# oxygen. The mole fraction of oxygen in air is thus #0.21#, and using this, the partial pressure is #P_("O"_2) = (0.21)(630"mm Hg") = color(red)(132# #color(red)("mm Hg"# Answer link Related questions How do you do a steam distillation?
