We’re being asked to determine the gas that would have the largest 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

Based on the equation for μrms, 3 and R are constants. All of the gases are at the same temperature (100°C). The only difference the gases have is their molar masses (M).
