7. A solution containing the complex formed between Bi(III) and thiourea has a molar absorptivity of 9.32 x 103 L·cm-1-mol-1 at 470 nm. (a) What is the absorbance of a 6.24 x 10-5 M solution of the complex in a 1.00-cm cell? (b) What is the percent transmittance of the solution described in Part (a)? (c) What is the molarity of the complex in a solution that has the same absorbance as the solution in Part (a), but was measured in a 5.00-cm cell?
