Question

A gaseous mixture contains equal weights of $O_2$ and $S{O}_2$ is?

• A. 1 : 2
• B. 2 : 1
• C. 3 : 1
• D. 1 : 3

Answer 1

Answer: (B)

2 : 1

Let the weight of $O_2$ and $S{O}_2$ be x

then mixture ratio will be

$\frac{x}{32}:\frac{x}{64}\Rightarrow \frac{\frac{x}{32}}{\frac{x}{64}}\Rightarrow \frac{x}{32}\times \frac{64}{x}=2:1$
