A solution with a large amount of solute dissolved in a given amount of solvent.
A solution that cannot dissolve any more solute.
2. What is the unit for molarity?
grams per liter (g/L)
moles per liter (mol/L)
liters per mole (L/mol)
kilograms per liter (kg/L)
3. A substance that dissolves in a solvent to form a solution is called a .
4. The is the component that is present in the larger amount in a solution.
5. A solution containing the maximum amount of solute that can be dissolved at a given temperature is called a solution.
