 Okay, so let's try this next one. This next one says zinc is a shiny metal that's used in plating iron to prevent corrosion. So how many grams of zinc are in 0.356 moles of zinc? So I've read it up here. 0.356 moles of zinc. Do you know something that will convert moles to grams? Do you know a conversion factor that will do that? Yeah, the molar mass, right? Okay, so the molar mass converts moles to grams. So if we're going to do that, what are we going to put down here, unit-wise, everyone? The moles of zinc. And up here, unit-wise? Grams of zinc, right? Okay, so the molar mass, well that is grams per mole, of course, so that one mole on the bottom what's the grams that we're going to use? What is it of that? 65.4? 65.4. So let's cancel out our units, moles of zinc, moles of zinc, right there, and so what do we do? Just multiply 0.356 times 65.4. And how many significant figures is this going to go to? 23.3. Okay, so 23.3 grams of zinc. That's what I got. Did everybody get that same answer? Did you get that same answer? Did you use your calculators? Make sure you're doing them with me. I'm not doing them for my health.
