How much potassium nitrate do you think could dissolve in 100 mL of water at 60°C?
Your tool of choice here will be the solubility graph for potassium nitrate,
The solubility graph is a very useful tool because it tells you the amount of potassium nitrate that can be dissolved per
In order to find the solubility of the salt at
In this case, you can estimate that the solubility of potassium nitrate in water at
#color(darkgreen)(ul(color(black)("solubility " ~~ " 110 g / 100 mL water")))#
This tells you that a saturated solution of potassium nitrate will hold about
