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 (μrms), we will use the following equation:

μrms=3RTM

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