Root mean square speed 3RTM The most probable velocity. Online chemistry calculator to calculate root mean square RMS speed of gas using gas molecular mass valueThe root-mean-square speed u is the square root of the average speeds of the molecules in a sample of gas at a specific temperature and pressure. Root mean square velocity.
Root Mean Square Speed of Gas Calculator.
The velocity V in the kinetic gas equation is known as the root-mean-square velocity and is given by the equation V_rmsfracsqrtV_12V_22V_32V_n2N We use this equation to calculate the root-mean-square velocity of gas molecules at any given temperature and pressure. Vrms 3RT M v r m s 3 R T M where v rms is the root-mean-square of the velocity M m is the molar mass of the gas in kilograms per mole R is the molar gas constant and T is the temperature in Kelvin. M rms 3RTM ½ Where R Ideal gas constant 83145 kg m 2 sec 2K mol T Absolute temperature in Kelvin M Molecular weight of the gas in kilograms. This online chemistry calculator may be used to calculate root mean square velocity mean velocity aka average velocity and median velocity.
