Question

1.A sample contains a mixture of two dyes, A and B. The molar absorptivity coefficients for dye A are 31,000 M-1 cm -1 at 500nm and 1,000 M-1 cm -1 at 590nm and for dye B are 8,500 M-1 cm -1 at 500nm and 35,000 M-1 cm -1 at 590nm. In an unknown mixture of the two dyes, the absorbance at 500nm is 0.8021 and the absorbance at 590nm is 0.5407. What are the concentrations of the two dyes? [Dye A] = _______________ M [Dye B] = _______________ M

Please show steps and formula. Also all the significant figures

Explanation / Answer

A = Ecl

A = absorbance

c= concentration

l = the value in nano meter

E= coefficient

it is simplyfi by Beers labarts law
