A “Bayer” brand of aspirin was dissolved in some sodium hydroxide and transferred to a 100.0 ml volumetric flask and diluted to the mark with distilled water. A 2.6ml aliquot of this solution was transferred to a second 100.0 ml volumetric flask and diluted to the mark with iron (III) chloride solution. The concentration of the iron (III) salicylate complex was found to be 0.055mM. What was the original concentration of A.S.A (aspirin) in the original solution, in mM? Round...

0.6573 g of potassium iodate is dissolved and diluted to a volume of 100.0 mL. Then 25.00 mL of this stock solution is pipetted into a 100.0 mL volumetric flask which is filled to the mark with water. What is the concentration of the final standard solution in mol/L? Include units in your answer, and round the final answer to the correct number of significant figures.
