The second method involves determining the Osma clarity from the polarity. Now we're going to say if the polarity of a compound is known, then the Osma polarity for each of its ions can be determined by Osmo. Polarity equals number off ions okay, that are within that compound times the molar ity of the compound overall. So this is yet another way that we can isolate Osma polarity. Now that we've seen the second method, click on to the next video. Let's take a look at a question where were asked to calculate the odds more clarity off a particular ill.
