What is vapour density of O ₂ gas?

Options

  1. A8
  2. B16
  3. C32
  4. D22 4

Correct answer

B. 16

Step-by-step solution

The vapour density of a gas is defined as VD = M 2 , where M represents the molar mass. For molecular oxygen O ₂ , the molar mass is 2 16 = 32 g/mol. Substituting into the vapour density formula yields 32 2 = 16 . Among the given options, the correct value is B) 16 .
