When calculating for root mean square speed (μ_{rms}), we will use the following equation:

$\overline{){{\mathbf{\mu}}}_{{\mathbf{rms}}}{\mathbf{=}}\sqrt{\frac{\mathbf{3}\mathbf{RT}}{\mathbf{M}}}}$

- Molar Mass of CO = 28 g/mol → M =
**0.028 kg/mol**

Calculate the root-mean-square velocity of CO at 286 K .
