**Problem 7: Absorbance and Transmittance of a Bi(III)-Thiourea Complex**

A solution containing the complex formed between Bi(III) and thiourea has a molar absorptivity of \(9.32 \times 10^3 \, \text{L} \cdot \text{cm}^{-1} \cdot \text{mol}^{-1}\) at 470 nm.

**(a)** What is the absorbance of a \(6.24 \times 10^{-5} \, M\) 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?
