Map Sapling Learning 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. RT 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- m2,s2 What is the rms speed of O2 molecules at 439 K? Number What is the rms speed of He atoms at 439 K?
