The recommended procedure for preparing a very dilute solution is not to weigh out a very small mass or measuring a very small volume of a stock solution. A sample of KMnO4 was dissolved in the water and made up to a volume in a 500-mL volumetric flask. A 2.000-mL sample of this solution was transferred to a 1000-Mlvolumetric flask and diluted to the mark with water. Next, 1.00 Ml of the diluted solution were transferred to a 250-mL flask and diluted to the mark with water.
a. Determine the concentration of the final solution.
b. Determine the mass of KMnO4 required to directly prepare the final solution.
