Video Transcript

so we want can we want rather Louis structure. So we want first now the formula with these the formulas And then we can draw the voice structure. So we know where are you know the mom eyes and also the percentage we got Not Eve 19.7 present of not for Jim and a 3 80 horn. Three Suzanne of Florrie the mass in the molecule in the compound. So we assume we have 100 grand Sample this camp. Oh, Then we have 90 90.7 not June and 80.3 ground Floren. So it now could knows him. The mauler of an Aborigine Ownby goes thio point Whoa oh to mole. And the moral of foreign law equals two. We're born to two seven Well, which, based on, um divide I well, a massive each element this fortune on this is around non chain is a roughly member eso Now we want calculate formula So we divide by the list mall with 1.1 point 46 Well, you know one. Not again. A full quarter to 27 divided by 107 Well, cuckoo is three flooring now The basic from their wells at three, which has 71 star, 70 one gram per mole. But when we gave a is 70 a more so which will consistent based on the model mass of a gentleman, because there has several, Um, there are several, uh, decimal of the hand, the and the numbers. So this is constant number. So our formula would be an three. And she was good. No, look at Lewis structure. It would be so now. General shares three on dance for him. The look, this guy's going to seven.
