The concentration of Fe2+ in a sample is determined by measuring the absorbance of its complex with ferroxine. The sample, measured in a 1.00 cm cuvette, has an absorbance of 0.254. The reagent blank in the same cuvette has an absorbance of 0.015. What would be the absorbance reading for each of these two solutions if measured in a 7.00 cm cuvette? A sample Areagent blank =

**Determining the Absorbance of Fe²⁺ in a Sample** The concentration of Fe²⁺ in a sample is determined by measuring the absorbance of its complex with ferroxine. The sample, measured in a 1.00 cm cuvette, has an absorbance of 0.254. The reagent blank in the same cuvette has an absorbance of 0.015. **Question:** What would be the absorbance reading for each of these two solutions if measured in a 7.00 cm cuvette? - \( A_{\text{sample}} = \) [Box for input] - \( A_{\text{reagent blank}} = \) [Box for input]
