A test solution of aluminum nitrate, Al (NO3)3, must be made that contains 20.0 mg/cm3 of the metal ion. If 1500.0 cm3 of the solution is desired, how many grams of the solute with mass measured as Al(NO3)3 • 9H2O must be used? What is the molarity of the solution? What is the molarity of the aluminum ion? What is the molarity of the nitrate ion?
