Shannon Owen · Answer 1

From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.

That means that 100 g of water at 40°C can dissolve 63 g of KNO3.

A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.

Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.
