6、The Dietary Supplement solution used in the experiment was diluted from the original concentrated supplement as purchased. Calculate the average concentration of iron(II) in the original supplement (in μgmL of liquid), using your average answer to QS and the dilution factor found on the on the label of the Dietary Supplement dispensing bottle. The reciprocal of the dilution fraction is called the dilution factor. For example, if the dilution is 1:250, the dilution fraction equals 1/250. Multiply the average iron(II) concentration in the diluted sample by the dilution factor (250/1 in this example) to find the average concentration of iron(II) in the original Dietary Supplement as purchased (concentrated). 7. Calculate the number of mL in a 4.0 fluid ounce bottle of liquid (such as a Dietary Supplement) given the conversion that there are 29.6 mL in one (1) fluid ounce. Show your answer in scientific notation to the correct number of significant figures. Based on your answer to Q7 and using the answer to Q6 as a conversion factor, calculate the total amount of iron(II) in micrograms (ug) from a 4.0 fluid ounce bottle of Dietary Supplement as purchased (concentrated). Show your answer in scientific notation to the correct number of significant figures. 8. vert micrograms 4.0 flui answer in scientific notation to the correct number of significant figures. from Q8 to milligrams to get the total amount of iron(I) from a d ounce bottle of Dietary Supplement as purchased (concentrated). Show your 9. Con 10. Deseribe the relationship between the concentration of iron(I) and sample color.
