Water is added to 25.0 mL of a 0.866 M KNO _ solution until the volume of the solution is exactly $500 \mathrm{mL}$. What is the concentration of the final solution?

Has put the given information in the problem because the volume of the final solution is greater than the original solution. This is our delusion process, keeping in mind that in a delusion, the concentration of the solution decreases. But the number of the morals of the solute remained the same. Using the formula were more clarity multiplied by volume off concentrated solution will be called to polarity multiplied. Revel you off the value decision. We get the volume off diluted solution as 0.4 tt em.

This question was asked to find the initial volume a solution with initial concentration off 0.33 Moeller that opened dilution yields a concentration off 0.25 Mueller with the falling of 25 minutes. So we asked to find the initial volume. And if you have to find initially only more concentration or anything like that, this question screams out for C one everyone equal c two b two, which is saying that that moves off the initial solution should be the same, moves off the final solution. So the most potential solution should be called the most of the final solution. So essentially we can write an expression that states that concentration initial turns volume initial should be equal to concentration. Final terms. Walling Final The scene of the initial about moles should be sequel to the final. Most of one delusion, given this, reacts to find the initial wallet so we can sell for the initial volume initial well and should be equal to, uh, concentration. Final terms of bowling final divided by the initial concentration. Now all we have to do is find out which of these values represent the terms here and self with the initial walk. So when solving for this we you've been given the initial concentration. The initial concentration here is 0.3 three Moeller. Our final volume is 25 millilitres in our final concentration is his opening zero to five fuller. Now we can sell for initial ruling. Initial volume is going to be equal to our concentration final, which is 0.0 to five Moeller times all final walling which has been given us 25 milliliters divided by our initial concentration which has been stated to museum 0.33 Well, so it's old. This yields a value of 1.8 nine. Really? So this means that initially we had 1.8 and millionaires and 0.33 morning upon dilution, we prepared 25 miles off points every 25 fuller solution

This is problem 65 of Chapter 14 Solutions. So in discussion, we have to find out the modularity of at CL solutions. So what we have given, we have given more clarity and one that means polarity before dilution. That is 12 molar. We want that mean volume before delusion that is 10 ml and polarity em to that after delusion that we have to find out And the volume after a delusion that is given to 50 ml So here this one represents before delusion and the two represents after delusion So these are the subscript that we have to use So apply the modularity equation. And when we win, that is equal to m two. We do. Okay, so now just put the value. So the value of m one that means 12 into we won 10. I am, too that we have to find out and we're 2 to 15. So the value of M two comes out to be 1 20 upon 2 50. Okay, so on solving we get the value of polarity. That is 0.48 Moller. So it means we can say that the modularity of, uh, it sealed solution prepared by and the looting 10 ml of concentrated acid to our total volume of 2 50 ml is point for eight Moller. Hence more clarity point for it, Moller.

We can use the delusion equation for this problem. We've got the first volume multiplied by the first polarity would be equal to the new volume multiplied by the new polarity which we don't know when we solve. For now, the diluted polarity we get 0.29 Mueller.
