The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule. 3RT rms speed where R-8.314 J(mol K) and. is molar mass in kilograms per mole. Note that a joule is the same as a kg m2s2 What is the rms speed of N2 molecules at 277 K? Number m s What is the rms speed of He atoms at 277 K? Number m/s
