What is the ratio of velocity of sound in hydrogen `(gamma=7//5)` to that in helium `(gamma=5//3)` at the same temperature?

The ratio of the velocity of sound in hydrogen (gamma= (7)/(5)) to that in helium (gamma= (5)/(3)) at the same temperature is (rho_1:rho_2=1:2)

The ratio of the velocity of sound in Hydrogen gas (gamma=7/5) to that in Helium gas (gamma=5/3) at the same temperature is sqrt(21/3).

The ratio of the velocity of sound in Hydrogen gas (gamma=7/5) to that in Helium gas (gamma=5/3) at the same temperature is sqrt(21/3) .

The ratio of the velocity of sound in hydrogen gas to that in helium gas at the same temperature is

Find the ratio of velocity of sound in helium (gamma =5//3) and that in oxygne (gamma=7//5) . Given the molecular weights of Helium and Oxygen are 4 and 32 respectively.
