**Problem**: What is the rms speed of He atoms at 295 K?

###### FREE Expert Solution

We’re being asked to calculate for the root mean square speed of He at 295 K.

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

$\overline{){{\mathbf{\mu}}}_{\mathbf{r}\mathbf{m}\mathbf{s}}{\mathbf{=}}\sqrt{\frac{\mathbf{3}\mathbf{R}\mathbf{T}}{\mathbf{M}}}}$

µ_{rms} = rms speed,

R = 8.314 J/(mol·K)

T = temperature, K

M = molar mass, kg/mol
