Now, suppose instead I want to find one molecule. What's the kinetic average of one molecule of gas? Not 1 mol. Well, remember, a mole has an avocado's number of molecules. So I simply take my formula and divide it by N. So three times R times two divided by two N. The reason I singled out the R and the N is because this guy is known as a Boltzmann constant. In other words, scientists use some value k that equals r divided by n. So we replace this R divided by n with k called the Bolton constant, and our equation becomes three times k times t over two.
