🤓 Based on our data, we think this question is relevant for Professor Goldsby's class at FSU.

Solution: Perfluorinated compounds are hydrocarbons where most or all of the hydrogens have been replaced by fluorine atoms. Perfluorinated solvents have a number of interesting and exploitable properties. For example, oxygen is very soluble in perfluorinated solvents. and they have been investigated as temporary means of supplying oxygen in the case of very premature births before the lungs are fully developed. The Henry's law constant for C7F14 is 2.5 x 10-2 mol/L•atm at 25°C, roughly ten times greater than the Henry's law constant for water at that temperature.   A. Calculate the concentration in M of oxygen dissolved in C 7F14 exposed to air at 25°C. Air is 21% oxygen.           B. The concentration of oxygen in the umbilical vein is in the neighborhood of 20 mg/100 mL of blood. Convert your answer from Part A to mg/100 mL
