Question

Consider a mixture of 2 mol of helium and 4 mol of oxygen. Compute the speed of sound in this gas mixture at 300 K

Answer 1

The mixture of helium and oxygen

Helium is an mono atomic, C_{v1, =} \(\frac{3R}{2}\)

Oxygen is an diatomic, C_v2 = \(\frac{5R}{2}\)

According to laplace correction, Speed of sound,
