Problem

A linear absorbance versus concentration calibration yields the equation

A = 0.42c

, where

A

has no units and

c

is in

\text{mol L}^{-1}

. If the path length of the cuvette used in the experiment is

0.80\,\text{cm}

, what is the molar absorptivity

\epsilon

(in

\text{L mol}^{-1}\,\text{cm}^{-1}

)? a)

3.4\times10^{-1}

5.3\times10^{-1}

4.2\times10^{-1}

1.9\times10^{0}
