A mixture of krypton and oxygen gases is maintained in a 5.65 L flask at a temperature of 56°C. If the partial pressure of krypton is 0.248 atm and the partial pressure of oxygen is 0.308 atm, what is the total pressure in the flask? __________ atm The amount of oxygen present in the blood depends in part on the partial pressure of inspired oxygen in the trachea, PIO2. This can be calculated from the barometric pressure, the fraction of O2 molecules in dry air, and the vapor pressure of water at body temperature (because inhaled air is humidified in the trachea). 20.9% of the molecules in dry air are O2 molecules and the vapor pressure of water at body temperature (37 °C) is 47 mm Hg. Taking the total pressure of the humidified inhaled air to be equal to the barometric pressure, calculate the PIO2 for a person in Boulder, CO (elevation 1650 meters), if the prevailing barometric pressure is 645 mm Hg. PIO2 = _________mm Hg
