A. 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?

What is an example of a physical property?

What type of matter is made of only one kind of atom

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
