Formula and explanation
Formula: v(rms) = √(v²) = √((3 k B T)/(m)) = √((3RT)/(M)) Applicable conditions: Ideal gas, equilibrium state. Explanation: A statistical average of molecular speeds. v(rms) is the root - mean - square speed, m is the mass of a single molecule, M is the molar mass of the gas, R is the universal gas constant.
