 So, if I write this down, it's again a conversion start question. So I start with 56.0 grams of aluminum chlorine and I want to end up with grams sodium chloride. So I need to convert. So if I plan this, you've seen in the previous question, from the chemical reaction equation here, I know that my mole conversion factors, if there's nothing written here, that means you're assuming a 1. So we know for each one mole of those, I get 3 moles of those. So I can go from mole to mole. Now I want grams to grams, which means I definitely need to convert first to mole. So mole, aluminum chloride, I'm going to go to grams aluminum chloride. And at the very end, I want to go to grams sodium chloride. So it goes at the top, and then probably coming from mole, sodium chloride. And in between, I had mole sodium chloride and mole aluminum chloride. Here, I can write the numbers from here. So I have the 1 here and I have the 3 here. Now the question is, how do I get the other ones? How do I get this one here? So this one is again previous chapter. This is why I told you that in the class, you have to be fast finding these molar masses because you don't want to spend too much time on it. So I want to know one mole, aluminum chloride, is how much? So one mole, aluminum chloride, is one times the mass of aluminum. Here, 0.698 plus 3 times the mass of chlorine, 0.3545 is 0.698 plus 3 times 0.545 is 133.33. So that's what goes here, 133.33. And now the other one, one mole sodium chloride, one mole here, is one times the sodium. So my sodium is over here. So it's 0.599 plus 1 times the chlorine, 0.3545 is here. And this is 22.99 plus 35.45, it's 58.44 gram. So this goes here and here we have the gram on top, so 58.44. And now I'm typing everything in my calculator. So 56 divided by 133.33 times 3 divided by 1 times 58.44, which gives me 73.6 grams of sodium chloride. So I'm going to start with 26 and then I'm going to write it as 26.
