Problem

A researcher records an absorbance of 0.335 for a

5.00\times10^{-5}

M solution of a dye in a 2.00 cm cuvette. What is the dye’s molar absorptivity at the measurement wavelength? (a)

7.71\times10^{3}\;\text{L\,mol}^{-1}\,\text{cm}^{-1}

(b)

3.35\times10^{2}\;\text{L\,mol}^{-1}\,\text{cm}^{-1}

(c)

3.35\times10^{3}\;\text{L\,mol}^{-1}\,\text{cm}^{-1}

(d)

6.70\times10^{3}\;\text{L\,mol}^{-1}\,\text{cm}^{-1}
