Question

A group of chemists measured the absorption spectra of different concentrations of a newly

synthesized dye in a cuvette with a 0.40 cm path length. The data can be found in the spreadsheet

accompanying this problem set. Calculate the peak molar absorption coefficient for the dye (to three

significant figures).

A group of chemists measured the absorption spectra of different concentrations of a newly synthesized dye in a cuvette with a 0.40 cm path length. The data can be found in the spreadsheet accompanying this problem set. Calculate the peak molar absorption coefficient for the dye (to three significant figures).

Explanation / Answer

log A = - (E. Conc. length of the tube)/2.303

log(0.036) = - (E . 0.3 .0.4)/2.303

E = 27.705
