\(20 \mathrm{~mL}\) of gas \(A\) and \(10 \mathrm{~mL}\) of gas \(B\) diffuses through a porous membrane separately in 1 minute. If the vapour density of \(B\) is \(X\), what is the vapour density of \(A\) ?
- A \(2 x\)
- B \(4 x\)
- C \(\frac{x}{4}\)
- D \(\frac{x}{2}\)
Answer & Solution
Correct Answer
(C) \(\frac{x}{4}\)
Step-by-step Solution
Detailed explanation
Rate of diffusion \(\propto \frac{1}{\sqrt{\text { Molecular mass }}}\) Molecular mass \(=2 \times\) vapour density Rate of diffusion \(\propto \frac{1}{\sqrt{2 \times \text { vapour density }}}\)…
