how long= separation/mean speed
I assume you know separation
From the average separation between air molecules at STP, and their mean speed, estimate how long it would take one molecule to move into the region occupied by another. Assume that air consists mainly of nitrogen molecules.
how do i do this question? so far i think its this but pls correct me if im wrong:
v(rms)=sqrt 3kT/m
v=sqrt(3x1.38x10^-23x273.15 / 4.6x10^-26) = 495 m/s
is this right? what should i do from here?
