So for one condition, for one volume in one mode, this guy equals the second condition, v two over n two. The same thing. The same results we saw in Charles Law and also in Boyle's Law. Except in Boyle's Law it was p times V equals p two times V two. Now this guy is equal to the constant, because remember, no matter what volume or number of mold we're talking about, as long as this is true, our constant will be the same. So both this guy and this guy equals the same constant.
