Problem

Which equation correctly expresses the quantitative relationship among absorbance

A

, molar absorptivity

\varepsilon

, path length

b

, and concentration

c

for a monochromatic measurement of a solution? a)

A = \dfrac{\varepsilon}{b c}

A = \varepsilon b c

A = 2.303\,\varepsilon b c

A = \sqrt{\varepsilon b c}
