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.
|Fluorocarbon||Solubility (mass %)|
Infants 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.
