Problem

A solution of Compound X has a molar absorptivity of

2.4\times10^{4}\,\text{L\,mol}^{-1}\text{cm}^{-1}

525\,\text{nm}

and a concentration of

1.2\times10^{-5}\,\text{M}

. Two cuvettes are available. (a) Calculate the absorbance if the solution is placed in a 1.00 cm cuvette. (b) Calculate the absorbance if the solution is placed in a 5.00 cm cuvette and state which path length yields a reading inside the optimal range 0.10–1.00.
