At 40°c how much potassium nitrate can be dissolved on 300g of water?

From the solubility curve, we can deduce that at 40°c can dissolve in 300g of water.
The term solubility refers to the amount of solute that can dissolve in a given mass of solvent. We know that the solubility of a solid in a solvent depends on temperature hence the solubility curve is a plot of solubility against temperature.
