The rms speed (in m / s ) of oxygen molecules of the gas at temperature 300 K , is

Options

  1. A483
  2. B504
  3. C377
  4. D346

Correct answer

A. 483

Step-by-step solution

The rms speed is given by v_ rms = 3 R T M₀ where, aligned R & = gas constant T & = Temperature of the gas and M₀ & = Molecular weight of the gas & = 3 8.3 300 32 10⁻³ & =483 ~m / s aligned
