🤓 Based on our data, we think this question is relevant for Professor Firtha's class at San Bernardino Valley College.
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).
Which of the following gases will have the largest root mean square speed at 100◦C?
