The speed of sound in oxygen at S.T.P. will be approximately: (Given, . R =8.3 JK ⁻¹, =1.4 )

Options

  1. A315 ~m / s
  2. B333 ~m / s
  3. C341 ~m / s
  4. D325 ~m / s

Correct answer

A. 315 ~m / s

Step-by-step solution

At STP Temperature, T=273 ~K Molecular mass of oxygen, M =32 10⁻³ ~kg Speed of sound is given by v = RT M = 1.4 8.3 273 32 10⁻³ =314.8541 315 ~m / s
