The Speed of Travelling Waves

The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is:

The velocity of sound in hydrogen at $0°\mathrm{C}$ is $1200 \mathrm{m} {\mathrm{s}}^{-1}$. When some amount of oxygen is mixed with hydrogen, the velocity decreases to $500 \mathrm{m} {\mathrm{s}}^{-1}$. The ratio of ${\mathrm{H}}_2$ to ${\mathrm{O}}_2$ by volume in this mixture is $\frac{256}{n}$, given that the density of oxygen is $16$ times that of hydrogen. Write the value of $n$.
