20 ~mL of gas A and 10 ~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 ?

Options

  1. A2 x
  2. B4 x
  3. Cx 4
  4. Dx 2

Correct answer

C. x 4

Step-by-step solution

Rate of diffusion 1 Molecular mass Molecular mass =2 vapour density Rate of diffusion 1 2 vapour density aligned & r_A r_B = V_A / t_A V_B / t_B = 2 vapour density of B 2 vapour density of A & r_A r_B = 20 / 1 10 / 1 = 2 x 2 vapour density of A aligned Vapour density of A=x / 4
