- 3. What is the mole fraction of an isopropyl alcohol(C2H7OH) alcohol made by 70% by mass? a.) What is the mole fraction of water?You want to reach a high boiling point in an aqueous system, so you increase the pressure in the reaction flask. You find that the water boils at a temperature of 166.8 °C. What is the pressure in the reaction flask? (Given: ΔH°vap(H2O) = 43.4 kJ/mol) (Show work please, and to 1 decimal place)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
