354668 The speed of sound in an ideal gas at a given temperature \(T\) is \(v\). The rms speed of gas molecules at that temperature is \(v_{r m s}\). The ratio of the velocities \(v\) and \(v_{r m s}\) for helium and oxygen gases are \(X\) and \(X^{\prime}\) respectively. Then \(\dfrac{X}{X^{\prime}}\) is equal to
