## Question

The speed of sound waves in a mixture of helium and neon at 300 K and at a pressure of 76 cm of Hg was found to be 758 m/sec. The densities of helium and neon are respectively 0.1785 and 0.8999 g/litre and γ of mixture is 1.667. What is the ratio of He and Ne in the mixture?

### Solution

5:1

Given, density of He = 0.1785 g/litre, density of Ne = 0.8999 g/litre.

Let the ratio be *x*:1.

Solving for *x*, we get the ratio **5:1**.
