The solubility curve tells you *exactly* how may grams of a solute will dissolve in a given amount of solvent and *any* temperature.
You can use this curve to answer almost any question you might be asked about solutes dissolving in solvents, ESPECIALLY Is the solution unsaturated, saturated or supersaturated?
How much NaCl will dissolve in 100 grams of water at 50 degrees Celsius?
