A solution is prepared by dissolving 0.222 2 (0.000 2) g of KIO3 [FM 214.001 0 (± 0.000 9)] in enough water to prepare a 50.00 mL of solution. The tolerance of the volumetric flask used to make the solution is 0.05 mL. a. What is the concentration of the solution (and the relative error of the concentration) in Molarity? b. A 5.00 (±0.01) mL aliquot of the solution is diluted in a 100.00 (±0.08) mL volumetric flask. What is the concentration of the diluted solution (and the absolute error of the concentration
