Question

The vapour density of ozone is

• A. 16
• B. 32
• C. 24
• D. 48

Answer 1

Answer: (C)

24

Answer 2

We know that,
Molecular weight of compound or molecules $=2 \times V \cdot D$.
Vapour density $(V. D.)$ of ozone molecules
$=\frac{ M \cdot wt \text { of } O _{3}}{2}=\frac{48}{2}$
Hence, $V. D$. of $O _{3}$ is $24$
