Question

A gas with formula $	ext{C}_n	ext{H}_{2n+2}$ diffuses through the porous plug at a rate one-sixth of the rate of diffusion of hydrogen gas under similar conditions. The formula of gas is

Prashant Kotian · Accepted Answer

Correct answer: C. 1/6 = sqrt(2/M). M = 72. 14n + 2 = 72 -> n = 5 (C5H12). Therefore, correct answer is C.
