![The Beer-Lambert law you'll be using to determine the concentration of an unknown is A = ebc
where A is the absorbance measured on the spectrometer, e (epsilon) is the molar absorptivity in
M cm1, b is the path length of the cell (the diameter of the cuvette which is filled with solution),
and c is the concentration of the solution in M.
