Determine the boiling point of an aqueous solution that is $2.50 \mathrm{m}$ ethylene glycol $\left(\mathrm{HOCH}_{2} \mathrm{CH}_{2} \mathrm{OH}\right) ; K_{\mathrm{b}}$ for water is $0.52^{\circ} \mathrm{C} / \mathrm{m} .$ Assume that the boiling point of pure water is $100.00^{\circ} \mathrm{C}$

Let's suppose we have three different die solutions of varying concentration. If I were to ask you without any other information, which of these solutions is the most concentrated? You'd likely guess the one on the left because the solution is more colored and opaque. But how can we explain this on the molecular level? To do this? Let's go ahead and assign each of these containers. The concentration the first one will assume is 10.5 Moeller. The second one will be half at 10.25 Mueller, and the most dilute solution will be 0.1 Mueller. Now, as a reminder, Capital M or molar, ITI is simply equal to the number of moles present and a certain volume in leaders. So 0.5 Mueller it's the same a 0.5 moles per leader, 0.25 moles per leader and 0.1 moles per leader. So, assuming that we look at the same amount of volume, we should notice that from here to here there will be half of many moles present. And from here to here there will be 1/5 the number of most present. Let's do that. So let's take little sections to zoom into from each of our solutions. Assuming these sections are the same size. Let's see what we see. Okay, I'm gonna represent dye molecules, Justus Blue Spheres. I'm just going to draw random amount in here, drawing them different sizes. But that's they should be the same size. Let's just just make that clear. Okay, 123456789 10. So I drew 10. That's just a random number just to start with. Let's assume we looked in here and we happened to see 10 blue dye molecules. If that were the case, we would assume that in this half of concentrated solution, we would see half the number of molecules half the number of moles or blue dye molecules. So instead of 10 I should see five. And lastly, with the most dilute solution, we should have 1/5 the original number of blue dye molecules. And so, instead of 10 we will simply have to present. And because there's less dye molecules to absorb light, more light is passing through and the solution seems clearer. And now you can explain this on the molecular level

Hello students welcome back in this question. I have to build That 0.2 model 0.2 model projects is 20% ionized in the solution. And I'm also given clear equal to 1.86 Calvin par morality. So the freezing point of the solution will be so first of all and given that 20% ionized so L5 will be equal to 20%. That is I can say it is a quarter 0.2. Right? So we know that alpha Is equal to I -1, divided by N -1. By because it is the I have a tax write checks will associate something like this. Right? So a value of and will be too so that is why uh this uh I can write I can put the value of in here so 0.2 will be equal to I -1. The verified to minus country. So from here I get the value of I To be equal to 1.2. Right so now I have to calculate the entities so the entirety of the people I ks m so their party s would be equal to 1.2, multiplied by 1.86. multiplied by 0.2. Okay so this will be called to 0.4464. So I can write approximately as 40 0.45. Right? So now I have I know that the 30th is nothing but delta did not have minus pf Right? So since I have to calculate the value of P f so this will be equal to 0.45 is equal to zero minus. So he s will come out. People do mhm -0.45° seven years with this little bit. My answer. Thank you.
