Inga [223]

The partial pressure of O2 in your lungs varies from 25 mm Hg to 40 mm Hg. What mass of O2 can dissolve in 1.0L OF water at 25.0oC when the O2 partial pressure is 40. mm Hg? Since the normal Water solubility of oxygen at 25oC and pressure = 1 bar is at 40 mg/L water, the partial pressure is only40 mmg Hg

Mass of 02 dissolve = (40 mmHg/760 mmHg)*( 40 mg/L) (1 L) =2.10 mg O2 dissolved
