Question

The vapor density of Carbon dioxide$\left(C{O}_2\right)$

• A. $\mathbf{32}$
• B. 16
• C. $\mathbf{44}$
• D. $\mathbf{22}$

Answer 1

The correct option is D

$\mathbf{22}$

Part one : What is vapor density

• The vapor's or gas's density is related to that of Hydrogen $\left(H_2\right)$ is called vapor density.
• This is the ratio of molar mass of the gas and the molar mass of Hydrogen $\left(H_2\right)$.

Part two: Vapor density of Carbon dioxide$\left(C{O}_2\right)$

• The molar mass of Carbon dioxide$\left(C{O}_2\right)$ is $44$
• The molar mass of Hydrogen $\left(H_2\right)$ is $2$
• So,

$$\begin{gathered} vapordensity=\frac{44}{2} \\ vapordensity=22 \end{gathered}$$

Hence option(d) is correct. vapor density of Carbon dioxide$\left(C{O}_2\right)$ is $22$.
