You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C₃₄H₃₂FeN₄O₄, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 34.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?   -don't prematureley round

1. A stock solution of I2 is standardized using a 0.1430 g sample of pure ascorbic acid. The titration to the starch endpoint required 25.45 mL of the I2 solution. Calculate the molarity of the I2 solution. 2. A vitamin C tablet was divided into three equal mass portions. One portion was crushed into a fine powder, dissolved in water, and titrated with the standardized solution from question 2 (above). The titration to the endpoint required 27.60 mL of the I2 solution. Calculate the number of milligrams of vitamin C that are in the original tablet.
