v \alpha \frac{1}{M} \Rightarrow \frac{v_{H_{2}}}{v_{O_{2}}} = \sqrt{\frac{M_{O_{2}}}{M_{H_{2}}}} = \sqrt{\frac{32}{2}} \Rightarrow \frac{v_{H_{2}}}{v_{O_{2}}} = \frac{4}{1}

 

Effect of density on speed of sound -

\frac{V_{1}}{V_{2}}= \sqrt{\frac{\gamma _{1}}{\gamma _{2}}\times \frac{\rho _{2}}{\rho _{1}}}

 

- wherein

\gamma _{1}\; and\; \gamma_{2} are ratio of specific heat.

\rho _{1}\; and\; \rho _{2} are densities.
