Dry air is 78.08% nitrogen, 20.95% oxygen and 0.93% argon with 0.04% being other gases. If the atmospheric pressure is 760.0 torr, what is the partial pressure of oxygen in dry air? a 20.95 torr b 159.2 torr c 600.8 torr d 760 torr
Added by Michele H.
Step 1
Given that dry air is 20.95% oxygen, convert this percentage to a decimal by dividing by 100: Mole fraction of oxygen = 20.95% / 100 = 0.2095 Show more…

Dry air contains 78.08% nitrogen (N2), 20.095% oxygen (O2), and 0.93% argon (Ar). Calculate the partial pressure of each gas in a sample of dry air at 760 mmHg.
