Solution:
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 %)

CF₄ 0.0015

CClF₃ 0.009

CCl₂F₂ 0.028

CHClF₂ 0.30

For CClF₃, calculate the molality of a saturated solution.
