Base on maxwell-boltzmann distribution,we can calculate the average velocity of gas molecule .
i read a book and it proves like that
average velocity=[itex]\int vf(v) dv[/itex]
I don't understand why we don't have to divide it by N because we should be calculating the average,but not the total.
Would anyone tell me where i went wrong

f(v) is a probability distribution, not the total number so you have already divided by N when calculating the probability distribution.

by multiplying each bin of the velocities, you already normalize the velocity distribution
