All iron in 4.00 g of iron ore sample, which was dissolved in an acid solution, was converted to Fe2+ which was then titrated with 0.200 M KMNO4 solution. In this titration all iron is oxidized to Fe3+ and MnO4 to Mn²*. If 27.45 mL of KMNO4 solution is required to the end point, determine 1. How many grams of iron content is in the iron ore sample. 2. The yield percentage of iron in the sample. 3. If the iron in the sample is present as Fe2O3, what is the mass percentage of Fe2O3 in the sample.

The blood alcohol C2 H; OH level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of Cr*+ (aq) and carbon dioxide. The reaction can be monitored because the dichromate ion (Cr2 O,²) is orange in solution, and the Cr³* ion is green. The unbalanced redox equation is Cr2 O,2 (aq) + C2H; OH(ag) → Cr³* (ag) + CO2 (g) If 40.35 mL of 0.0711 M potassium dichromate solution is required to titrate 27.5 g of blood plasma, determine the mass percent of alcohol in the blood.
