WebApr 5, 2024 · The root mean square (R.M.S) speed $ V $ of the molecules of an ideal gas is given by the expression, $ v = sqrt(\dfrac{{3RT}}{M}) $ and $ v = sqrt(\dfrac{{3KT}}{m}) $ where R is universal gas constant, $ T $ is the absolute (Kelvin) temperature, m is the molar mass, K is Boltzmann’s constant and M is the molecular mass. WebInstead, we need to find the square root of the average of the squares of the velocities: (-1)^2 + (-2)^2 + (-3)^2 + 1^2 + 2^2 + 3^2 = 28 28 / 6 = 4.67 The square root of 4.67 is 2.16. So the root-mean-square speed is 2.16 m/s, …
