There is a mixture of gases in dry air, with an atmospheric pressure of 760 mm Hg. Calculate the partial pressure of each gas for the examples below:
A. 20.7% oxygen, 78.2% nitrogen, 0.4% carbon dioxide
B. 45% oxygen, 41% nitrogen, 3% carbon dioxide, 11% hydrogen
C. 79% oxygen, 15% nitrogen, 5% carbon dioxide, 1% argon
Partial pressure = Patm × % gas in atmosphere.
