If you dilute 20.0 $\mathrm{mL}$ of a 3.5$M$ solution to make
100.0 $\mathrm{mL}$ of solution, what is the molarity of the dilute
solution?

This question is a simple dilution question where we can use the dilution equation. M one B one equals M two V. Two. We can rearrange it to solve for the new polarity, the new polarity being equal to M one B one over V. Two. So the original polarity is 6.25 million liters. We need to have the volume units the same. So one is in leaders, one is in milliliters, I'll convert the milliliters two leaders 25.5 mL is point oh 255 leaders. I then divide by five and I get 319 molar hcl. We do the exact same calculation but with different numbers for part B we have an original modularity of two times 10. The negative to Mueller and an original volume of 8.25 mL. Because both volumes are in mill leaders, I don't need to convert them and then divide by 12 mil leaders and I get the final concentration of 1.38 times 10 to the negative to Mueller potassium iodide.

So basically what I have is that I have a solution of a specified volume under specified concentration on it. It has a particular amount of solute in terms of more on what I do is that I add water, which means I have increased the volume. However, the amount of my soldiers or the number of moles is the same, and I'm asked to determine C two knowing for two. That's so from here I could determine the number of Moore's and I could use that in order to determine C two. So in my first example, the number of moles of HCL it's basically the concentration towards the volume. In my case, I'm given the concentration to be 6.25 variety on varieties. Moore's per liter. So one, let's write it on the side one, um vehicles arm liter. Andi, I need to multiply by the volume, which is 22.5 milliliters. As you could see the units I different. I'm going to do this trick. It's is if I multiplying by one here. I want to cancel the leader in the denominator. So I put one return denominator. Andi, I know that one liter is equivalent to 1000 liters. Discusses that with this. This cancer is allowed to this on what I end up having for the number of wall 0.14 Well, 6 to 5 months from there I could determine constitution to which is the number of malls which is the same between woman tool of every tool, which is a point to 14 moles divided by the volume or multiplied by its reciprocal. On my new volume is operate five liters on this would give me Oh, point 319 mostly leader or m The second example exactly the same. First I conclude the number of malls, which is basically my volume times a concentration, which is 8.25 milliliters, and he I'm gonna do the conversion. I know that there were 1000 milliliters for each leader on C one is to attend to two months to call spirit liter. And so I would get 1.65 times 10 toe off minus four walls. All right. On s. So my second concentration is basically the number of walls over the new volume which is 1.65 times 10 to the minus score moves. Andi. Yeah, I'm gonna divided by No, I have 12 milliliters and I'm gonna do the same trick of conversion again. They have 1000 milliliters for each litre on what I end up getting is 4.138 more spirit litter, which is big toe variety.

What is the polarity of a solution that contains one million Moeller of Salyut per mil leader solution? We simply need to carry out this calculation by dividing the Mila moles by the middle leaders. The Millie's cancel and we're left with moles per leader or one Moeller.

Hi everyone. So in this question they ask you 25 miller 0.56 smaller stress separation diluted to a volume appoint 24 Yemen. What is the majority of the resulting solution now? Let us consider. Okay. And one of even with the popularity of consent interest to a software so that is equal to m to veto. So I am to be to be the modularity and volume off die duties to yourself. Okay. So M one they have given 10.56 into given 25 that is equal to and two of dilute hashtag S A for Gdansk in two ways 1 25 and therefore M two of valued. You're so forth. It is illegal to 0.56 in two 25. You worried by 1 25 that is equal to 0.112 more Lord and therefore people I am too of Nitwit. I should pass up for 1962 0.11 tomorrow. Mhm. Thanks.
