Question

Recovery standards are a necessary tool for determining exactly how much of a particular analyte you are able to extract from a sample. You have a recovery standard that contains 4.0 mg Fe/1.0000 g sample, d.w. Your analysis determines that you extracted 3.5 mg Fe from 1.0101 g sample. A sample that you ran in parallel with the recovery standard returned a measurement of 1.7 mg Fe in 0.9582 g sample. How much iron (mg Fe/g sample) is actually present in your sample?
