   The solubility of the fluorocarbon in water was calculated from the kinetic data derived from observations of particle growth in aqueous emulsions in which Ostwald ripening takes place. The kinetics of coarsening of  particles was observed by photon correlation spectroscopy on a Coulter N4 instrument. The calculation was based upon the Lifshits-Slezov equation.

Source and Purity of Materials:
   (1) Commercial reagent. 97 % pure, passed through a column with Al2O3 before use.
   (2) Double distilled and deionized.

Estimated Errors:
   Solubility: Twice that of other results.
   Temperature: ± 1 K.
