# Problem: Calculate the root-mean-square velocity of SO3 at 286 K .

###### FREE Expert Solution

When calculating for root mean square speed (μrms), we will use the following equation:

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

µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol
