Question

Calculate the vapor density of sulfur dioxide, ${\mathrm{SO}}_2.\left[\mathrm{O}=16,\mathrm{S}=32\right]$

Answer 1

Step 1: Given information

The given compound is Sulfur dioxide $\left({\mathrm{SO}}_2\right)$. It is required to calculate its vapor density.

Step 2: Calculation of molecular weight of Sulfur dioxide

Molecular mass of Sulfur dioxide$=32+\left(2\times 16\right)$

$=64\text{g}$

Step 3: Formula used for vapor density

$\text{Vapor density=}\frac{\text{Molecular mass}}{2}$

Step 4. Calculation of vapor density of Sulfur dioxide

$\begin{array}{rcl}\mathrm{Vapor}\mathrm{density}\mathrm{of}{\mathrm{SO}}_2& =& \frac{{\text{Molecular mass of SO}}_2}{\text{2}}\\ & =& \frac{64}{2}\\ & =& 32\end{array}$

Hence, the vapor density of Sulfur dioxide is $32$.
