A 100 mL stock standard solution of 0.008M KMnO4 will be prepared by weighing 0.126 grams of solid KMnO4, it will be diluted to the mark with water (this is the stock solution). Four 10 mL of standard solutions: 0.00008M, 0.00016M, 0.0004M, and 0.0008M will be prepared from the previous stock solution.
- Calculate how many mL of the sample stock solution are necessary to make 10 mL of 0.00008M, 0.00016M, and 0.0004M. (how will it be made)
- Calculate how many mL of the sample stock solution are needed to make the 0.0008M solution.

A Na2CO3(MM = 105.99 G/MOL) standard solution is prepared by transferring 2.4814 grams of primary standard-grade sodium carbonate to 250.0mL volumetric flask, dissolving the sample in about 100 mL of distilled deionized water and diluted to the mark. A 25.00mL aliquot is taken and titrated with 40.18mL of HCl solution. Calculate the concentration of the HCl solution.

The recommended procedure for preparing a very dilute solution is not to weigh out a very small mass or measure a very small volume of stock solution. Instead, it is done by a series of dilutions. A sample of 0.8521 g of KMnO4 was dissolved in water and made up to the volume in a 500.0−mL volumetric flask. A 2.000−mL sample of this solution was transferred to a 1000−mL volumetric flask and diluted to the mark with water. Next, 10.00...
