The following experiment was carried out using a newly synthesized chlorofluorocarbon .Exactly 50 mL of the gas effused through a porous barrier in 157 s.The same volume of argon effused in 76 s under the same conditions.Which compound is the chlorofluorocarbon? A) C₂Cl₄F₂ B) C₂ClF₅ C) C₂Cl₂F₄ D) C₂Cl₅F E) C₂Cl₃F₃

Using Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. Comparing the effusion times, the molar mass of the chlorofluorocarbon is calculated to be approximately 187 g/mol, which corresponds to C₂Cl₂F₄.
