Okay, so here we have five grams of delirium, and we're trying to find the mass of mercury that would be in this quantity of delirium. So if you were to just rich out, take this quantity and touch off the Tillery. Um, atoms for mercury atoms? Yes. We're going to take this weight and multiply it by, like, a molar mass factor. But let me show you. Have we get that? Quite So what? We are going to the state. What is a given here is that Adams of delirium are equivalent to the Adams of of Mercury. Correa Adams is number of atoms is equal to mulls times every guy just constant. And that moles is a prevalent to mass over mama mass. So that if we just no substitute, we get mess multiplied by have a gardener's number divided by Miller maps. Is it close to Adams? And I just said that I was a Chilean Equal items of mercury. So let's right that. So I'm going to say claria, Miss T and a mercury is h. So here we have massive Hillary, um divided by more massive chiller, sometimes have a guardian's constant multiplied by massive Mercury, you know, is equivalent to Sorry. Two massive Mercury Dubai, about more massive mercury times have a gorgeous constant. Mm Adams. At least two Adam speak a little bit. Yeah. So right off the back To what we can't Sloat. You can get rid of any to some both sides, and then you're right is negligible. And now we can just easily so for mass of mercury. But it's over looking for so then as a mercury, it's equivalent to this over here. Massive till Irianto had by Mo message delirium. And now we're going to multiply by more massive mercury on both sides. Get it over here. Yeah, quite straightforward. So we have 2.2 four grams of delirium. Now, here is the molar mass factor. So my little masters to get your periodic table my here and you can find that while the molar mass of mercury's quite large, it's 200 grams per mole, 200.59 grams per mole in the muller massive delirium is, um 1 27 0.6. Yeah, and delirium is my Lloyd, and it's in a Group 16 scams for more. All right, so if we do this quick calculation we get. Oh, sorry. It's not too pointy for over the previous ones. Actually, five. But I wrote up top five games. Not apply by that. Yes, Five grams. It's Lereah. So then, yes, that's how we get seven point 86 Do you? 7.6 grams of mercury? Uh huh.
