The following experiment was carried out using a newly synthesized chlorofluorocarbon .Exactly 50 mL of the gas effused through a porous barrier in 172 s.The same volume of argon effused in 76 s under the same conditions.Which compound is the chlorofluorocarbon? A) C₂Cl₂F₄ B) C₂Cl₄F₂ C) C₂Cl₃F₃ D) C₂Cl₅F E) C₂ClF₅

Question

Quizplus · Accepted Answer

The effusion rate of a gas is inversely proportional to the square root of its molar mass. The fact that the chlorofluorocarbon takes longer to effuse than argon means that it has a higher molar mass. Of the choices given, only Option B has a higher molar mass than argon because it has two fluorine atoms in addition to its chlorine atom.
