Question

When a mixture containing equal moles of $He$ (molar mass $4$) and $CH_4$ (molar mass $16$) is allowed to effuse through a pinhole into a vacuum for a very short initial interval, which of the following statements are correct?

Prashant Kotian · Accepted Answer

Correct answer: A,B,C,D. Since , effuses twice as fast (A, D). Consequently, the effused gas has more than (B), leaving the original mixture depleted of , meaning its mole fraction inside decreases (C).
