Question

Density of ozone relative to methane under the same temperature & pressure conditions is :

• A. 1
• B. 3
• C. 1.5
• D. 2.5

Answer 1

The correct option is B 3

Density of ozone relative to methane under the same temperature & pressure conditions is 3.

$PV=nRT$

$P=\frac{\rho }{M_w}RT$

$M_w$ is molecular weight.

$\rho \propto M_w$

$\frac{{\rho }_{O_3}}{{\rho }_{C{H}_4}}=\frac{48}{16}$

${\rho }_{O_3}=3{\rho }_{C{H}_4}$
