Problem

A solution of a colored compound has an absorbance of 0.600 when measured in a 1.00 cm cuvette at a concentration of 0.0150 M. What is the molar absorptivity of the compound at this wavelength? (a) 4.0×102  L mol−1 cm−14.0\times10^{2}\;\text{L\,mol}^{-1}\,\text{cm}^{-1} (b) 6.0×101  L mol−1 cm−16.0\times10^{1}\;\text{L\,mol}^{-1}\,\text{cm}^{-1} (c) 2.7×101  L mol−1 cm−12.7\times10^{1}\;\text{L\,mol}^{-1}\,\text{cm}^{-1} (d) 4.0×101  L mol−1 cm−14.0\times10^{1}\;\text{L\,mol}^{-1}\,\text{cm}^{-1}
