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 0.7287 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 mL of the diluted solution was transferred to a 250.0 mL flask and diluted to the mark with water. Round your answer to 4 significant digits. Part 1 of 2 Calculate the concentration of the final solution. Part 2 of 2 M X Calculate the mass of KMnO4 needed to directly prepare the final solution. x

You are given a solid that is a mixture of Na2SO4 and K₂SO4. A 0.205g sample of the mixture is dissolved in water. An excess of an aqueous solution of BaCl₂ is added. The BaSO4 that is formed is filtered, dried, and weighed. Its mass is 0.298g. What are the percent compositions by mass of Na₂SO4 and K₂SO4 in the sample?
You are asked to determine the percentage of the components of a mixture containing sodium iodide, NaI, magnesium hydroxide, Mg(OH)2, and barium sulfate, BaSO4. The total mass of your mixture sample is 4.82g. First you extracted the NaI from the mixture with water and filtered insoluble Mg(OH)2 and BaSO4 from the solution, containing the NaI. After evaporating and drying the filtrate, you find that you have recovered 0.95g of NaI. When you react the insoluble residue of Mg(OH)2 and BaSO4 with 3M HCl, the Mg(OH)2 dissolves. After decanting the supernatant liquid containing aqueous MgCl2 from the insoluble BaSO4 and drying the solid, you recover 2.04g of BaSO4. Finally you add 3M KOH solution to the aqueous solution to precipitate the Mg(OH)2. After filtering thesolution and drying the precipitate, you recovered 1.21g of Mg(OH)2. Calculate the percent Mg(OH)2 in the original sample mixture.
