A 0.28g steel sample containing an unknown % of Mn is dissolved and digested. The solution is tested at multiple wavelengths using a spectrophotometer. The values are as follows: (wavelength, absorbance) (450, 0.09) (500, 0.69) (525, 1.15) (550, 0.90) (600, 0.11). A standard sample of steel is 0.56% w/w Mn. A 0.3g sample is dissolved in dilute nitric acid and digested. Using a spectrophotometer set to 525 nm, the absorbance value for the dissolved steel solution is 0.650. What is the % Mn in the unknown sample?
