A solution is prepared by dissolving 0.2222 (0.0002) g of KIO3 in 50.00 (0.05) mL
(i) Calculate the molar mass of KIO3 with its associated uncertainty to the correct number of significant figures.
(ii) Find the molarity and its uncertainty with an appropriate number of significant figures.
(iii) Would the answer be affected significantly if the reagent were only 99.9% pure? Why or why not?
