We’re being asked to determine the gas that would have the smallest root mean square speed at 100°C.
When calculating for root mean square speed (μrms), we will use the following equation:
µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol
Which of the following gases will have the smallest root mean square speed at 100°C?
