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

. Using a

1.00\,\text{cm}

cuvette at

540\,\text{nm}

(

\varepsilon = 4.20\times10^{3}\,\text{L}\,\text{mol}^{-1}\,\text{cm}^{-1}

), the absorbance recorded was

0.430

. Calculate the percent error in the analyst’s concentration determination based on this measurement, relative to the true concentration.
