What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water. • Describe the relationships between volume and amount of solute to concentration. • Explain how solution color and concentration are related. • Calculate the concentration of solutions in units of molarity (mol/L). • Use molarity to calculate the dilution of solutions. • Compare solubility limits between solutes.
