[3. Beers Law will be used to measure the concentration of FeSCN(aq) ion, at a wavelength like the one you chose in question #2. If the absorbance of an 0.01004 M solution of FeSCN'(aq) is 0.977 in a 1.0 cm cuvette (b), what is the "molar absorptivity" (ɛ) in the Beers Law equation. A² = e* b [F¢SCN(aq)] ( is molarity solve for ɛ Now, if a second solution of FeSCN(aq) has an absorbance of 0.431 in a 1.0 cm cuvette at the same |wavelength, what is the concentration of FeSCN'(aq) in the solution ?
