 Okay, so let's figure out this so we've got all this information. We put it all together, right? If we got 0.832 moles of water How would we figure out how many moles of magnesium sulfate pentahydrate that did we start right? We would have to do this conversion Right, so we have this many moles of water and we know from the chemical equation you guys recall One mole of magnesium sulfate pentahydrate equals five moles of water So should we be able to with this information get how many moles of magnesium sulfate pentahydrate we started out with? So how would we do that? Help me out So yeah, so we're gonna have to multiply by something right because this is chemistry class We've got a unicorn and so what are we gonna put on the top here? Want well the whole thing. What do we have to put one everybody please one whole? magnesium sulfate Pentahydrate if you don't know how to say that yet something that you need to know how to say And on the bottom five moles Why did you put that on the bottom? Because you want to cancel out moles of water Does that cancel out moles of water? Does that give us what we want? Does that give us what we want? So all we got to do is plug and chuck And I just did it from what I had saved over Can we figure out how many moles of magnesium sulfate the dried magnesium sulfate we produced? Could we do that? Yes, how will we do that? What would be the conversion factor how about let's write the conversion factor here instead of doing that problem Let's just write the conversion factor. So we started out with moles of water. So that would be So what would five moles of water equal to one mole of magnesium sulfate right because it's a one to one to five Any questions on something like that
