Question

The Beer-Lambert Law, A = cl, shows the relationship between absorbance (A) in spectrophotometric measurements, and the following parameters:

the concentration, c, of the solution (usually given in M)

the length of a cuvette, l, (usually given in cm)

the molar extinction coefficient, .

If a sample is measured to have an absorbance of 0.86, at a concentration 0.0032 M and in a cuvette with a pathlength of 1.0cm, determine the molar extinction coefficient, , in units M-1 cm-1.

Enter your numerical answer in the box below, to 2 decimal places. Do not enter units.
