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

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 ^{o}C, and their solubilities in water at 25 ^{o}C and 1 atm fluorocarbon pressure are given as mass percentages.

Fluorocarbon | Solubility (mass %) |

CF_{4} | 0.0015 |

CClF_{3} | 0.009 |

CCl_{2}F_{2} | 0.028 |

CHClF_{2} | 0.30 |

For CClF_{3}, calculate the molality of a saturated solution.

We’re being asked to calculate the molality of ClF_{3} given its solubility in mass percent.

**Mass** or **weight percent (% by mass) **is the percentage of a given element or compound within a solution.

The equation used to calculate for mass percent is shown below:

$\overline{){\mathbf{m}}{\mathbf{a}}{\mathbf{s}}{\mathbf{s}}{\mathbf{}}{\mathbf{p}}{\mathbf{e}}{\mathbf{r}}{\mathbf{c}}{\mathbf{e}}{\mathbf{n}}{\mathbf{t}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{m}\mathbf{a}\mathbf{s}\mathbf{s}\mathbf{}\mathbf{c}\mathbf{o}\mathbf{m}\mathbf{p}\mathbf{o}\mathbf{n}\mathbf{e}\mathbf{n}\mathbf{t}}{\mathbf{t}\mathbf{o}\mathbf{t}\mathbf{a}\mathbf{l}\mathbf{}\mathbf{m}\mathbf{a}\mathbf{s}\mathbf{s}}{\mathbf{\times}}{\mathbf{100}}}$
