Question

At 580 nm, the wavelength of its maximum absorption, the complex Fe(SCN)2+ has a molar absorptivity of 7.00 X 103 L mol-1 cm-1. Calculate

(a) the absorbance of a 2.50 X 10-5 M solution of the complex at 580 nm in a 1.00-cm cell.

(b) the absorbance of the solution in which the concentration of the complex is twice that in part (a)

(c) the transmittance of the solutions described in parts (a) and (b)

(d) the absorbance of a solution that has half the transmittance of that described in part (a)

 

answer letter d please
