List one concept that you are having difficulty with from Chapter 12. a. Why do you think that you are having issues with this concept? b. Write down a number of things thatyou do understandabout this one particular topic.
I am having some difficulty converting between the units of molality, mole fraction, molarity, etc. I know that this is probably the most difficult part of chapter 12, and if I can get this part down, I should succeed. a. I think I am having issues with this concept because there are several different units to convert, and using them in the proper manner is proving to be difficult for me. I think I need to do several more problems that deal with conversion to be able to feel 100% confident in my abilities. b. I understand each of the formulas and what they are to be used for. I understand what the units are for each of the types of concentration units. I understand when to use the formulas.
The step that seems to cause the most confusion for new learners is that the masses of the solute and solvent add to give the mass of the solution. This is used when converting to and from molality and/or mole fraction.
I am having problem with understanding the molality and how it is related to the density, especially if I am not given much information in the question. for example if I have the density, how is it possible to accomplish the molality through the density only.
I do not think that we can get the molality only from the density, we can get the molality from a weight percent or a solubility limit for a saturated solution.
Saturated Solutions A. I don't understand how much of the solution is solid and how much is liquid. Because of the liquid is in equilibrium with solid then doesn't that mean there is a precipitate? B. I understand that that if more solute is added it will precipitate
i am having some problem manipulating the given information and conversions between density, molality, and molarity. i understand the definitions, it is just understanding the flow of ideas and how to get from point a to point b.
The equations in chapter 12 were the hardest part for me to understand. I think it was mostly to do with the conversions to and from molality. But after going to the group study session that Ms. Nguyen set up and going over some problems it helped a lot.
