What molarity of ZnCl2 forms when 25.0 g of zinc completely reacts with CuCl2 according to the following reaction? Assume a final volume of 275 mL.
Zn(s) + CuCl2(aq)-ZnCl2(aq) + Cu(s)

Figure out the polarity of the silver nitrate solution. First thing we need to do is understand what the chemical reaction is. Its silver nitrate reacting with copper producing copper to nitrate and silver. And we see the two moles of silver nitrate react with one mole of copper to make one mole of copper to nitrate and two moles of silver malaria used to find as the moles of a substance. For leaders of the leader of the substance, Well for leader of the solution containing the substance. In this case, silver nitrate is the substance were considering. So we need to know the moles of silver nitrate and we need to know the volume of the silver nitrate solution. The volume of the silver nitrate solution was given to us at 75 milliliters, so we know this once we cover the mill leaders. Two leaders but we don't know is the moles of silver nitrate, but we can contain. But we can take the grams of silver that was produced and convert the grams of silver, two moles of silver and then using the stone geometry of the reaction covered the moles of silver to the mold two moles of silver nitrate and we get 2.318 times 10 the negative three moles of silver nitrate, the polarity that will be the molds that we just calculated of silver nitrate divided by the volume in middle leaders converted to leaders. And we get 0.309 Moeller silver nitrate.

If I have to 0.5 moles of ze NCL tube. This is a 1 to 2 ratio for my chloride ions. So what I can do is I consent it up as a problem for every one. No cozy and see out, too. I produced two moles of chloride, so therefore 2.5 times to produce five bowls of C L minus.

And this problem were given a new alloy that's 80% copper, 20% zinc and its density. And were you asked to find the morality of sick? Students struggle with this kind of problem because they feel like they don't know how much they're working with. And what you have to realize is that these air concentrations it doesn't matter if you have one cubic centimeter of this alloy or a whole ton of this alloy, the concentrations are going to be the same. So let's for the sake of simplicity and you can you can pick any amount that you want. But for the sake of for simplicity, let's assume that we have one cubic meter. That's the three of the alloy. If we have one cubic meter of the alloy, then we know that we have, uh, 8700 and 50 kilograms, right, because that's its DNC. So I found that using the density, So if that's my total mass, then I confined. How much mass corresponds to the copper and how much mass corresponds to zinc. Now, remember that for morality, what I need is moles of Salyut. In this case, copper is the Salyut and the solvent is the zinc because there's more zinc. Sorry, I have that backwards. I heard the backwards the copper. Okay, the copper is the solvent. That's what I should say. So the copper is a solvent and the zinc is the Salyut kick. So if we know that the total mass is 87 50 then that's in kilograms. Then we know that 20% of that is zinc. So I'm gonna write that as a decimal. That means that the mass that zinc is equal to 17,050 kilograms. Now I need moles of sink and I have more mass in grams per mole. So I'm gonna change this kilograms two grams multiplied by 1000. It's an outrageously large mass. But remember that we were trying to pick numbers that are easy to work with. So 1000 750 multiplied by that So many grams we have We're gonna divide by the Moler. Massive zinc. If we look up our periodic table, that's 65.38 grams of zinc. For every one mole of zinc. This is ink and what we find is we have 26,770 laws. I think I know that looks outrageous. That's only because we kicked a meter cute and that's a big number, and it's okay. So that zinc, that's her Salyut now we're gonna you find are solvent. Similarly, if our total mass is 8000 750 kilograms, the portion that corresponds to copper is 80%. So 800.800 is the percent that it's copper. That's equal to 7000 kilograms. And remember that for morality, we need kilograms of solvent. So we already got what we need there. So this is kilograms of covered, and now we have moles of sync, kilograms of copper. So we're going to read the morality as 26 770 moles of zinc divided by 7000 kilograms of copper. That's equal to three point eight to will allow. That's the lower Kay's M sick, where Malala starts stands for moles for every kilogram, then in part B, similarly, uh, same scenario. But now we're asked to calculate the polarity and polarity you'll recall is moles of Saul, you over leaders of solution. So again, uh, the moles of Saul, you We already found the the most desolate we already found that came out of the heart. A So we're gonna keep the same number of also, Saul, you That's the 20 26,770 rules of Zinc. Now we need the volume of the whole solution. Uh, this is relative so forward. We already found that the volume we assumed was one meter cube that we need to change one meter cube too. Volume. You should know that a meter cute is equal to 1000 leaders. That's just a conversion factor that you should know every little look up. And so we're able to write the polarity as 26 70 moles divided by 1000 leaders and find that this is equal to 26 point eight Moeller Capital M Zinc, where Mueller stands for malls for really

From this question. We know 25 form of thing has reacted, so we need to calculate how many, most of think by using the mess divided by its Moeller mess on. Based on the spell is to chemical equation, we can see the the racial off. Think the ritual think Call Reid is overthink equals to well over well, so the polarity overthink no zinc chloride equals to the most was in kora, divided by his volume.
