Mn was used as an internal standard for measuring Fe by atomic absorption. A standard mixture containing 2.00 microgram Mn/mL and 2.5 microgram Fe / mL gave a quotient (Fe signal / Mn signal) = 1.05. A mixture with a lovlume of 6.00 mL was prepared by mixing 5.00 mL of unknown Fe solution with 1.00 mL containing 13.5 microgram Mn/mL. The absorbance of this mixture at the Mn wavelength was 0.128, and the absorbance at Fe wavelength was 0.185. Find the molarity of the unkown Fe solution.
