1. You must have a table in your text or in your lab manual that gives the solubility of some of the salts at various temperatures. . I assume this is an experiment you are conducting. KCl is rather soluble.

2. In the question above this one it says refer to a solubility chart, but my professor never taught us how to answer these questions while using a solubility chart so I have no idea what to do. I've tried going to his office hours for help, but he's only there when I have a class.

It's the standard solubility chart (if you looked it up on google or something) but I have no idea how to answer the question.

3. You can't draw a graph on these boards but if its a table, can you either describe it or list the columns and temperatures?
You can't type information on this board in columns but you can do it this way, using periods for spaces
T........mass KCl/100 mL
10........a grams.
20........b grams
30........c grams
etc.

4. So, for KCl, using the graph...

T.....mass KCl/100 mL
10....30
20....32 or 33
30....35
40....38
50....41
60....44
70....46
80....49
90....52 or 53
100...56

5. Is the solubility of KCl then 46 grams/100 mL at 70 degrees C? (I don't know if that is the unit for you OR if you were just copying the unit I gave as an example.) If 46 g/100 mL, then
g in 50 mL = 46 x (50 mL/100 mL) = 23 g/100 mL.
