A 0.0000704 M sample of Compound X in a solvent has an absorbance of 0.316 at 528 nm in a 1.000-cm cuvet. The solvent alone has an absorbance of 0.066. Explain what is the molar absorptivity of Compound X?
A dissimilar sample of Compound X in the same solvent has an absorbance of 0.506 at 528 nm when measured with the same cuvet. Explain what is the concentration of this second sample?
