So we're keeping the reaction off a 16 point chromecast unnatural eight. We every 17 45 grandma by moving forward to form gives him for him. Not that natural, general saying and water. So, first of all, we have to balance the chemical reaction. Okay, so, uh, the cousins, everybody is, And then for the four way we have to add it to your phone. Over, Um, I'm gonna be in for, you know, to advanced. Ah, Number off for I. Okay, so we have helped him for bonds. We'll let the matter Jin's so left. We have two national from 92 99 for mom on the air. So we have four night stringent. Toto. So we had to put a, um too. Even the eventual. Okay, so and then we're looking at Ah ah, Hodgins. So on the left, we have eight hydrogen from the omnium irons. So we have to put four you find off the h two so much. You were the same number off Hodgins and then last but the nopal on these, we're going to check the lumber Oxygen. We have six on laughing system. Right. So we have the band's level reaction. Okay, so the question, their actual question is what you're looking at. Ah, how many grand while each substance still present at the annals of we should. Okay, so it may contain Paul. Our pulled it. And also, you can also counting our, um, reaction as well. Okay. So from people who were given the boot, um, the matter at mass off reactors, office over it had to find out that the bomb, Bos and then we had to see we have limiting regions. And which one will be the only Metin we agent? So first of all, that's convert to lumber. Move off. Council, naturally, are really fast. So Ah, we have calcium. 40.8 Plus, we have to night trade. Zion's, um for no one puts a 16 point. Sorry. 16. Ah, point overtime 34 Now a tree And that to off them. So it would be 1 64.1 gram per mo for calcium nitrate. You should be able to find, um, on your own. So we have 16 point. Do you wanna buy them with a mass? But I'm looking for the monument. So are the number one. Most would be corresponding to a single 10.1, though, to mo for calcium nitrate. So and Well, okay, so the number Momo's off moon Young four. Right, is we have our body mass divide by sort of master bomb with the mass. So we have the nitrogen, we have four. Ah, Hodgins. And then we have four reigned, Um, and these are around 37 point a one gram per move on another mass. So we have our, um, masts, 17.1 deal by 37.1 So we have lost their supports for, um 723473 Most off our I'm only in Florida. Okay. Okay. So, um, the established we had to file their limiting the agent. So you see, we have any. Okay, so let's say we want to come. Betty, we every cask your calcium. Naturally, what would be the man off the, um, I'm gonna go forward. We need So we have sealed point when those two times two. So, actually, we'll need, um, syrup on 204 More off. Moving forward to competing reaction. But you can also see that we have more than enough. And the reaction mixture. So therefore, um, the calcium, naturally is a limiting The Asian is a limiting reagents. So where we want to calculate the number more for the were acting. We're going to reduce the number more off calcium. Naturally. Okay, awesome night tree. Okay, so the next step is I'm just wet. Um, come over here, Father. Long bones mo off all the reactor Soon we're going to, you know, just number most accounts, um, night tree. So we're looking at them motorway show. And then from the motivation, we can found the lumber most of the way. Accents. So first off, for the first week at in the mall, away show is casting for right. The castle natural is 1 to 1. So you're also a super will want to When those who move forecast in four and then for nto I can see that the wager It's one, 22 So we have seen our super one over to mow off gassing night three times. Two Ah, for the number almost off that nitrogen. Well, no. Sorry, receiver boy. Oh, for Mo And then for war for watery. There we shall we want to four. So we just multiply our number most of calcium nitrate advice for So we have syrup 40.48 mills. All right, so, um, those other number, most of reaction at the end of reaction. So how about a lump on? Most of it is no more Paul It How about the lumber? Almost reacting. So for the number, almost we act in. Ah, the councilman. Niger's is already constant, so you don't have anything left, But we have some off the morning before I left. So the mmm four right laugh will be the actual months minus Darmon going to be happy of calcium nitrate. So we have sealed 1473 last for, um 0.204 So we have syrup or and chewing 69 Um, most off the, um I'm only, um four. Okay, so the last step is to convert all the number most back thio dumb ass by mother playing the limo. Most, uh, Bible in the mass. So for calcium fall right, Carol, Soon four. Right. We have syrup on 102 most times. The modem ass andi way have accounts in 40.8 Uh, plus, we have to Ah foreign, and then the total mass roughly of our seven for 96 gram for cancer in full. Right. Okay. We're going to do the same thing for dance, Jamal. Say so. We have about a natural into nitrogen, plus a one all citrine. Um, and then we won't buy Buy the lumber most we We have a 0.98 graham off our, um nto and the same for water. So we're safe for a four week, most times the mass of water. So you would be around seven point 34 grand. Okay, So how about ah moo MYoung fall? Right. So we just need to multiply. Um, our number one most. So it is for mourning for four. I should be a reaction. And the mass of it at the end of the reaction. We have civil for 269 Most times we have a 19 Children. Ah, for hydrogen. And then we have foreign. Ah, the total must would be nine point. Uh, now you six grand remaining. So these are the mass off the
