Okay, So in this question, they want us to calculate the maximum amount of P. Ford. I can be produced from one kilogram of fast, right? And then they say the faster I sample contained 75%. See a three parentheses, peel for parentheses to So how much see Ace Threepio for to do we have? Well, they say that we have one kilogram of foster. I've only 75% of that is See a three peel for two. So you multiply that by 75 divided by 100. Then we should get the amount of C A three p o for two. Right? So we get 2.75 kilograms. Let's convert this kilograms in two grams. So one kilogram is equal to 1000 grams and we get 750 grams of C A three p 04 to Okay, So the mole ratio of see a three p o for two is to to one, right. It's okay. So let's start setting up an expression that we can plug into calculated. So we have 7750 grams of C a three Pierre for two. Now we have to convert this into most first. So one mo off see a Threepio four is equal to it's equal to 310 0.18 grams promo. Right. So in order to figure out the molar mass, ivory figured it out before. But if you wanted to do it by yourself, are you gonna do is we have three Most of calcium Multiply it by the molar mass of calcium. Plus we have to most of potassium, right, because to outside the parentheses, that means we must fly everything in the parentheses by two to most of potassium times by the molar mass of potassium plus two times four. So we have eight moles of oxygen times by the molar mass of oxygen, and then you can figure out the mullahs mask. So in order to safe time, I've already calculated of the molar mass. So one So so far, we converted the 750 grams of C A threepio for two into most. So now let's look at the multiple ratio of this and this because this is the product. We're trying to see how much you can produce. So we have two moles of see a three I feel for two produces one mo of P four, right? One mo of P four is equal to 123.88 grams promo and I was gonna do now is just plunges into the calculator and we should get got 1 49.77 grams. If they want you to around a whole number, I guess it can be about 150 grams.
