So the reaction rich in Sulfur s eight with throwing gas. If we put it s f six. So we have 17 point Graham Also For how? What would be the massive foreign required to your company? We are. We've all this over. Okay, it's festival. We have the bonds to chemical reactions. So first up on star Ah, sell fair silver A silver. So how about foreign? We have 48 4 years under, right? And then on the latter we must have the same number off foreign. So I'm going to a 24 year from a foreign to make sure they're the same. Number four e. Okay, so they look So we're going to find the lumber almost off sulfur the sulphur for two poor old seven. But we have a day off them. So they move with the master to 56 for 56 Kuemper mo for S h. So the number most we have Ah, mass d y by the molar mass and it will be a 0.0 Ah 694 most Okay, um because we want to find ah, the mess off foreign. So we have to find a lump of more foreign. So the lumber more foreign. When we look at the more the way show we can see that women for each off the estate we must have 24 the foreign. So for this case of the willies ratio is 1 to 24. So, uh, we just have to multiply the limbo more by 24 times. And then we should we have our total on Momo's off foreign. So 1.167 and the massive foreign How we are going to mother fight our number most by the, um modem. Ask So for foreign, Gaston, move that mass. We refer t eat we we have thio foreign. So we have 38 time 1.67 and then we should be able to find it is 63.5 grand for foreign guests.
