Hemoglobin is a protein having a molar mass of 64500g/mol and containing four atoms of iron(II). When 73.5g of a sample containing an unknown amount of hemoglobin is analyzed by precipitating all the iron(II) as iron(II) phosphate, 0.500g of precipitation is collected. What is percentage of hemoglobin contained in the sample?

By Beer’s Law, determine the molar absorptivity of the iron (II) phenanthroline complex using maximum absorbance, the molar concentration of the standard iron solution, and the cell path length. I'm confused because on this lab we have calculated the max Wavelenth (497nm) and used a spectroscopy instrument to measue the max Absorbance at that wavelength for the other samples and unknown. Beers law seem simple, But how would I use it to find the molar absorptivity? SAMPLE (in ppm) Max...

A 0.1987 g sample of an unknown Ni(II) salt was put into solution and properly treated to form the solid nickel(II) dimethylglyoxime complex (molar mass = 288.917 g mol-1). When the precipitate was rinsed, dried, and cooled, it was determined to have a mass of 0.1763 g. Calculate the mass of nickel in the precipitate and the percent (by mass) of nickel in the original (unknown) salt sample. Please. Please show me detail work so that I understand this problem.If...

How do I find the weight precent iron (II)? We measured 1.0014 g of unknown iron sample and added 100.0 mL water. Then pipetted 10.00 mL of the first solution into a beaker and added 90.00 mL of water. Then added 1,000 microliters of the second solution to a plastic container along with the reagents needed to analyze it with a spectrophotmeter. This solutions total volume was 10.00 mL. I then measured the absorbance of this solution and got .019...

3) Cerium(IV) sulfate  is used to titrate a solution of iron(II) ions, with which it reacts according to Ce4+(aq) + Fe2+(aq) = Ce3+(aq) + Fe3+(aq) A cerium(IV) sulfate solution is prepared by dissolving 38.14 g of Ce(SO4)2 in water and diluting to a total volume of 1.000 L. A total of 17.82 mL of this solution is required to reach the endpoint in a titration of a 250.0-mL sample containing Fe2+(aq). Determine the concentration of Fe2+ in the original solution. answer:...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
