Explain spectrophotometric determination of food dyes

Reference no: EM13512483

How do I determine the concentration of mixed unknowns in a spectrophotometric determination of food dyes?
For example, I was given two unknown solutions
4302

4301

Each was ran through the spectrophotometer at red and green wave lengths
4302: 524 nm wavelength=9 T% and Absorbance of 1
628 nm wavelength= 7% and Absorbance of 1.3
4301: 524 nm wavelength= 4% T and Absorbance of 1.5
628 nm wavelength= 41 T% and Absorbance .39

From there, I have to determine the concentration of each unknown at each wavelength. If someone could please show me how to set this up to determine concentration that would be great
