An aqueous stock solution ("S") which is having 8.657 mg of gallium (Ga) per mL of solution is diluted in the following manner. A 3.00 mL aliquot of this solution is added to a 150.00 mL volumetric flask. Upon addition of the proper reagents, gallium is known to form an aqueous Ga+3-complex that contains one (1) Ga+3 cation per complex formed.
Next, sufficient deionized water is then added to the volumetric flask (and contents) so that the final solution volume is 150.00 mL.
This is solution "X". A 3.00 mL aliquot of solution "X" is added to a clean, empty
150.00 mL volumetric flask. Sufficient deionized water is then added so that the final solution
Volume is 150.00 mL. This is solution "Y".
Calculate the concentration (in M) of Ga in Solution S and determine the concentration (in M) of Ga+3(aq) in solution X and in solution Y.
