How do you figure out the saturation of a substance

Divide the mass of the dissolved compound by its molar mass to calculate the number of moles. In our example, this would be: Number of moles (NaNO 3)=21.9g /85 g/mole= 0.258 moles.

Explanation:

A solution is saturated if there is visible solute that is not dissolving in the solution. Additional solute added to an already saturated solution just forms a layer of solute separate from the rest of the solution, according to a chemistry lesson posted by Mountain Empire Community College.

If the temperatures of solutions are increased, the solubilities of solutes increase, which means more solute can dissolve in a warmer solution versus one at room temperature. Substances have set solubilities in different solvents, depending on the conditions of temperature and pressure. The normal conditions of temperature and pressure are 25 degrees Celsius and one atmosphere. Several factors affect the solubility of a substance. Temperature, pressure, size of the solute and stirring of the solution all contribute to the amount of solute that can dissolve.
