The ratio of rates of diffusion of gases (A ) and (B ) is (1: 0.707 ). If the molecular weight of (B ) is 32 , the molecular weight of (A ) is

Options

  1. A2
  2. B64
  3. C16
  4. D8

Correct answer

C. 16

Step-by-step solution

Rate of diffusion is inversely proportional to the square root of molecular weight. ( aligned i.e. R & 1 M R_A R_B & = M_B M_A 1 0.707 & = 32 M_A 1 0.499849 & = 32 M_A M_A & =15.99 16 aligned )
