A mixture of gases contains H 2 and O 2 gases in the ratio of 1 : 4 (w/w). What is the molar ratio of the…
- 1 : 4
- 4 : 1
- 16 : 1
- 2 : 1
Solution
\hline & & \mathrm{H}_2 & : & \mathrm{O}_2 \\
\hline \mathrm{W} / \mathrm{W} & \Rightarrow & 1 & : & 4 \\
\hline \text {Moles } & \Rightarrow & \frac{1}{2} & : & \frac{4}{32} \\
& \Rightarrow & 1 & : & \frac{1}{4} \\
\hline
\end{array}\)
i.e. 4 : 1
