# Problem: Fluorocarbons (compounds that contain both carbon and fluorine) were, until recently, used as refrigerants. The compounds listed in the following table are all gases at 25 oC, and their solubilities in water at 25 oC and 1 atm fluorocarbon pressure are given as mass percentages.FluorocarbonSolubility (mass %)CF40.0015CClF30.009CCl2F20.028CHClF20.30Infants born with severe respiratory problems are sometimes given liquid ventilation: They breathe a liquid that can dissolve more oxygen than air can hold. One of these liquids is a fluorinated compound, CF3(CF2)7Br. The solubility of oxygen in this liquid is 66 mL O2 per 100 mL liquid. In contrast, air is 21 % oxygen by volume. Calculate the moles of O2 present in an infants lungs (volume: 15.5 mL ) if the infant takes a full breath of air. Assume a pressure of 1 atm in the lungs.
