All right. So here we&#x27;re looking at, uh, quite a few, uh, chemical formulas and their molar masses. So let&#x27;s take a look at one mole of each of the following compound so we&#x27;ll do. Neon gas will do calcium solid, will you? Carbon dioxide? Yeah. Teoh calcium carbonate, which is a solid will do. Um, methanol, which is a liquid will do. Ethanol is a liquid, and we&#x27;ll do iron oxide, which is the all right. So here&#x27;s where we will take a look at the period table and start adding stuff together, right? So starting off with neon, what&#x27;s the molar acid beyond? We just take a look at periodic table, take a look at that average mass number, and that&#x27;s 20.180 grams per mole. Same sort of process for calcium, and we find that it&#x27;s 40 point 078 grams per mole for carbon dioxide. We add up, um, the mother mass of one carbon atom, which is 12.11 plus two times oxygen, which is 15 point 999 and this gets us once. We add all those two up 15.999 times two plus 12.11 That is 44.9 grams per mole. Calcium carbonate. So we&#x27;ve got Kelson here. We&#x27;ve got carbon here and we&#x27;ve got oxygen. So we need three times 15 999 for oxygen plus 12.11 plus 40.7 08 So once you add those two up, we get 100 point zero a six grams per mole. No for methanol. So we&#x27;ve got, um, four hydrogen total one there, three there. So it&#x27;s four times 1.8 France from old for hydrogen plus oxygen 15.999 plus one carpet 12.11 That&#x27;s gonna equal, UH, 12.11 plus 15.999 plus four times the quantity of 1.8 That&#x27;s going to get us 32.4 two grams per mole. Now for ethanol, that&#x27;s two times 12.11 waas 15 points 999 Plus, uh, I believe five times hydrogen, which is 1.8 That&#x27;s equal 45 0.6 grams per mole Now for iron oxides. We&#x27;ve got three times Austin 15.999 what? Two times iron, which is 55 point for five grand from all. And adding those two up, that is 143 point six eight eight grams per mole, and that&#x27;s that.

Okay, we&#x27;ll leave given here X and yeah, exited even minus cool. Minus one Beatle and one and two. I&#x27;m here affects your forgiven affects Johnson and G expense. And it&#x27;s also given both the funds and even here. And we put here that affects a year six Eddie and minus one, minus food and Vito. And here this is zero. This is who won find minus B and minus six. This is a table He had been with effects and yet given here effects and be exit even here in the table on we have to find here that fruit in there root. And then f minus one minus at deedle. If it&#x27;s a deal and this is minus, this is d he to And this is quest and less. Yeah, minus to to be weighed. I mean, many people. I&#x27;d d minor. What? And we here see that? We have putting it at minus one. This is minus one and minus. One is quickly here. Tender city and minus Deal after deal. Here you go to minus one. This is minus minus one on this is minus and G to G to here. This is and do you Goto here, minus six with minus six on. This is and plus minus two. Is it minus and minus two years. Six. So this is here. Six. So we put here six divided by G two and G minus six. This is minus six. Multiplied here and minus one. This G minus one minus when it was full. This is multiplied here. Andi, we We know that here. Route in there. This is B minus minus one. This is cool. Minus minus six square. This is 36. Okay. And plus six on. We hear Boardman formula for here first waiting right here for six. Divided by yes, minus six. And this is multiplied here for on the six and six begins allowed on route in the before we consider to minus 36 on this. In here, minus four. I&#x27;m sure your fine city Tu minus 36 minus four on minus 40. Here. That is minus 30. I&#x27;m sitting here minus. It&#x27;s

well. First, start off by finding all the values from the table. The values that we need to know to solve. This expression at negative one is equal to three. F zero is equal to negative. One F of negative two is equal to six g of negative. One is equal to four and g of two is equal tonight. Here six. And we&#x27;ll take those values and will replace our expression with these numbers. So square root of three plus one, minus 36 plus six divided by negative six times for Let&#x27;s use our order operations. Starting off with our radical three plus one is four, and the square root of four is two minus 36 6 divided by negative. Six is negative. One times four is negative four. Then we&#x27;ll just subtract left to right and we&#x27;ll get a negative 38.

Yeah, X, he&#x27;s even here minus two minus one beetle. When doing this, access given on affects is also given Here that these six pretty minus one minus. Hold on. This is zero. And he exit door here. Even there. I think the excess here. It&#x27;s a deal. If it&#x27;s full, this is one minus three and this is minus six. We have to find here that Morgan? Yes. When this is F one minus. Yes. Needle more and minus G one. And the one square, the one who squared less. T one be right f minus one F minus one. Making life he to and we have to find here, so yes, After 11 Here, this is one and one equals minus four. So this is minus and minus and being taken to be more on F minus one minus one in more minus. And we want you here, G one. And this is one. And when you got there? Minus three. So this is minus B squared less on G one on one. Here. One in, minus on the right of way and F minus one. This is minus one and F minus. When you go to you, I replied here. And you too. And we put the very between minus six. This minus six on your reviewed here, that is, minus school. This is more than the minus pole. And this minus minus. This becomes a plus one. And this is minus three s quest. That is three square, that is nine. This is minus night. Plus, and this is here less. And you tear that is board. Much formula remains. First, we divide here. So this is minus three on. We can work in tow one by three. Multiply here minus six. And this yeah, three and three we can see on this is more than one minus one minus 40 because minus more minus nine and the city will cancel out on the minus minus one minus one. Multiplied way plus one for here when it with care minus one multiplied minus six. So more minus 33 This is minus nine minus minus six and must and then subject. So So this can be getting three plus six. This is nine. And this is minus night with Anthony nine minus nine cities. Que

we&#x27;ll take those values from the table and then we&#x27;ll plug them into our expression. So after we calculate after we identify the values from the table, let&#x27;s plug them in to our expression. We have absolute value. Negative for minus negative, one minus negative. Three square plus night of three divided by three times negative. Six. Once we start off with our absolute value, negative for this becomes a plus. Plus one is negative. Three of the absolute value of negative three is three. This is nine with a minus in front and then negative. Three. Divided by negative three is negative one or negative freedom. Other by positive through his negative one times negative. Six. It&#x27;s positive. Six. Adding this all together we get zero.

right. So the question wants us to complete a blank periodic table, and, uh, me bill, he troubled blocks within the table. Which SPG? Yeah. So the table looks like this. We have, Ah, something that looks kind of my dad. It&#x27;s gonna be like a scheme t. Yes. Okay. Dandy start dividing into roles and cool. Like Okay. No, I have, uh, no one on the news. Yeah. Two rules not certified in two columns. So we have another violators SPD year. So this is s block. It was too long. G Block six. Indie is between the S and P, and these old block is called, uh, if it&#x27;s that simple, not you.
