Problem

A chemist records an absorbance of 0.362 for a colored solution in a 1.00 cm cuvette at a wavelength where the molar absorptivity is

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

. What is the concentration of the absorbing species in the cuvette? (a)

2.50\times10^{-3}\,\text{M}

(b)

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

(c)

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

(d)

2.50\times10^{-4}\,\text{M}
