WebMar 24, 2016 · The root-mean-square speed is the most probable speed of any molecule of comparable mass in a system. The formula for the root-mean-squared speed is as follows: `V_(rms) =sqrt((3*R*T) / M)` where: Vrms= mean velocity of gas particles R = gas constant (8.3144626181532 J/(mol·K)) T = temperature of the gas M = molar mass of the gas WebFor any list of numbers holds: The root mean square (rms) is always equal or higher than the average (avg). Only if all numbers in the list are positive and equal then rms = avg. The reason...
