So I simply get one half times mass over molam mass times R and T. Now, remember, molar mass has units of mass divided by moles. So the mass will cancel, and moles will go on top, and we'll get one half the mass will cancel. So this M and this M will cancel. The moles will go on top, and we'll have R times T. So my file final representation of my kinetic or average kinetic energy is three times N times R times T divided by two, where N is our number of moles. So Suppose we have 1 mol of any gas. Well, since we have 1 Mol, our N will be one.
