### Video Transcript

in this question, we've been actually calculate the monuments of Egypt for win compounds. All right, so the 1st 1 is estate, you know, Scotland elements. We need to know what atomic massive each of these elements are. So the 1st 1 this estate sulfur looking the parent table, the mole on my ass off. So, for oneself, for Adam is 32 point. There are six Graham, spin, move. Right, But here we have eight. So you just won't buy that by eight. And that should give us 256 point for eight graspable. It's like I want to see five age eight. So for carbon, the moments of one coven Adamis told for 011 We have five governments were gonna multiply that by five. Plus, we have 12 insurgents. So we have 1.8 similar mass off 100 jin. But let that by 12. And our final result is Sony to point 151 Grasp more For what? See, we have scanned iam so feet. Hey, So is this when we scanned your once over it? But we have to scan Diem's here right to the more mass off once Candy Madame is 44 0.956 Well, they have to have more fun that way, too. And then we have three suffers. So long, Mrs 32 Points here. Six. Movement of my three. And for oxygen, we try. We have 12 Oxygen's. It's gonna be 15.999 Tool In the moments of this sense of being 37 8108 grams more for party, which is asset on we have three Kurban six hydrogen, it's and one oxygen. Just like what we've been doing before. Carbon, we have 2.11 times three. Well, hydrogen. We have one point. There's very eight by six, and lastly for oxygen we have one Swifty on 999 This should end given us 58 point. They're eight grams more and lastly for glucose C. Successful six of six governments 200 system six. Oxygen's. Just think what we did before, So why is everyone one times six. The current's class will please. There there eight strove for the legends class. This time around, we have 15 6 oxygen's of 15.999 six national and they've given us. 180 went one of closest gramps before. That is how we determined that bull a mask off East wing bones.
