Question #1497c
1 Answer
At about
Explanation:
In order to be able to answer this question, you must have some information about how the solubility of potassium nitrate,
A useful tool to have at your disposal is the solubility graph for potassium nitrate, which looks like this
Your goal is to find the temperature at which
Since no additional information was provided, you can assume that the density of water is equal to
#100 color(red)(cancel(color(black)("mL"))) * "1.0 g"/(1color(red)(cancel(color(black)("mL")))) = "100 g"#
Now, look for
From the point of intersection, draw a vertical line until you intersect the horizontal axis, i.e. the axis that shows the temperature.
Your line should fall somewhere in between
You can thus say that you can dissolve
