Anyone do this chem lab already? Its called Determination of the Iron Content in a Vitamin Tablet. I want to know if these calculations are correct. I have attached instructions on how to do the calculations (which do contain some important points) and the calculations themselves (you might need to zoom in to see them clearly).
Show transcribed image text Anyone do this chem lab already? Its called Determination of the Iron Content in a Vitamin Tablet. I want to know if these calculations are correct. I have attached instructions on how to do the calculations (which do contain some important points) and the calculations themselves (you might need to zoom in to see them clearly). Calculations Calculate the concentration of Fe(II)in each of the standards (dilution calculation). Construct a Beer s Law plot from the standard data, as described in the introduction to Chapter 5. From the Beer s Law plot or from the Beer’s Law equation for the line, determine the concentration of iron(ll) in each of the diluted unknown solutions. Since the volume and concentration of the diluted unknown solutions are now known, the mass of iron in the diluted unknown solutions can be read ily determined. This diluted unknown solution contained 1.00 mL of the original 10.00 mL (unknown solution) prepared from the tablet. Calculate the mass of Fe(II) in the 10.00 mL unknown solution. This unknown solution was prepared from a weighed subsample of the whole tablet. Calculate the mass of Fe(ll) in the whole tablet.
