A compound composed of carbon, hydrogen, and chlorine effuses through a pinhole 0.411 times as fast as neon. What is the molecular formula of the compound?

Question

Quizplus · Accepted Answer

The rate of effusion is inversely proportional to the square root of the molar mass. Given that the compound effuses 0.411 times as fast as neon, we can set up the equation: (Rate of compound / Rate of neon) = sqrt(Molar mass of neon / Molar mass of compound). Solving for the molar mass of the compound gives approximately 119 g/mol, which corresponds to CHCl₃.
