I wanna say 3,398.08 but let me know if that sounds very off
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.
Photosynthesis is the process by which plants take in carbon and use it for energy and produce oxygen.
It's just H20 but with 3 water molecules
