Answer:

Well, you lines up the #y-"ordinate"# with the #x-"abscissa"#.

Explanation:

And so using the graph, we could make a saturated solution of #KCl# in water by dissolving #44*g# to #100*mL# to water......

At #10# #""^@C# the least soluble substance is #"potassium chlorate"#, #KClO_3#.

As is typical, SOLUBILITY of a solid solute INCREASES with INCREASING TEMPERATURE. And the SOLUBILITY of a gaseous solute DECREASES with INCREASING TEMPERATURE (interrogate the solubilities of #"ammmonia"#, #"sulfur dioxide"#, and #"hydrogen chloride"#). And this can be rationalized in that when we dissolve a solid, we have to supply energy to BREAK the solute-solute bonds.
