Question

What is the solubility of potassium nitrate in water? And how is `"solubility"` defined?

Answer 1

`"Solubility"` `=` `"Moles (or mass) of solute"/"Volume of solution"`

Explanation:

Typically we report a solubility in `mol*L^-1` or `g*L^-1`, and nitrate salts are exceptionally soluble. This site reports a solubility of `316*g*L^-1` at `20` `""^@C`.
