A solution containing the complex formed between Bi(III) and thiourea has a molar absorptivity of 9.32x10^3 Lxcm^-1xmol^-1 at 470 nm. What is the absorbance of a 6.24 x10^-5 M solution of the complex in a 1.00-cm cell? What is the percent transmittance of the solution? What is the molarity of the complex in a solution that has the same absorbance, but was measured in a 5.00-cm cell?
