Question

The density of $CC{l}_4$ vapour at $0^0$C and $1atm$ in $g/L$ is:

• A. $11.2$
• B. $77$
• C. $6.26$
• D. Can't be found

Answer 1

The correct option is C $6.26$

From Ideal gas equation,

$P=\frac{dRT}{M}$

Molar mass of $CC{l}_4=154gm$

$T=0^{0}C=273K$

$P=1atm$

$\Rightarrow d=\frac{PM}{RT}$

$\Rightarrow d=\frac{1\times 154}{0.0821\times 300}$

$\Rightarrow d=6.26g/L$

Hence, option $\left(C\right)$ is correct.
