Chemistry

Fe(III) forms a complex with thiocyanate, Fe(SCN)²⁺,that has a molar absorptivity of 7.00 x 10³ at 580 nm. A5.00 ml aliquot of a solution that contains 47.4 ppmFe³⁺ is reacted with excess thiocyanate and diluted to25 ml.
a) What fraction of 580 nm light is absorbed in a 1.00 cmpathlength cell by this solution?
Consider 5.00 ml of this solution diluted to a volume of50ml
b) What fraction of 580 nm light is absorbed in a 1.00 cmpathlength cell by the diluted solution?
