In preparing a standard solution of K3[Fe(CN)6], 0.1248 g of the solid was weighed using an analytical balance with an uncertainty of 0.1 mg. Then the solid was dissolved and transferred to a 50 ml volumetric flask and the flask was filled to volume with water. Using a transfer pipette, you transferred 1 ml of the solution to a 100 ml volumetric flask and the flask was filled to volume with water. Calculate the molarity of the final solution with uncertainty. All the glassware used was Class A. The tolerances of Class A glassware can be found at http://www.titrations.info/pipette-burette.
