WebThe partial pressure of any gas can be calculated by: P = (Patm)— (percent content in mixture). P atm, the atmospheric pressure, is the sum of all of the partial pressures of the atmospheric gases added together, Patm = PN2 +PO2+ PH2O+ PCO2= 760 mm Hg. The pressure of the atmosphere at sea level is 760 mm Hg.
