An aqueous emulsion of perfl ubron (perfl uorooctyl bromide) and water is being considered for an artifi cial blood. The perfl ubron emulsion contains 24 g perfl ubron per 100 cm3 solution. A plot of the amount of O2 dissolved in the artifi cial blood (mL/100 cm3 ) versus O2 partial pressure at 37°C is shown in the following fi gure. The volume of oxygen (mL) that is soluble in the blood is measured as the volume of pure O2 that leaves the gas phase at 37°C and 1 atm. The density of perfl ubron 1.93 g/cm3 is and its chemical formula is C8F17Br.

(a) Consider this emulsion being used as a blood substitute. Estimate the amount of oxygen, in [mol], dissolved in a liter. State any assumptions that you make.

(b) Compare the result from part A with the amount of oxygen that would be found in pure water.

(c) Determine a value for the Henry’s law constant for O₂ in C8F17Br in [bar]. State any assumptions that you make.
