A standard solution of bromocresol green at pH 12 was prepared with a concentration of 1.030 x 10-5 M. The solution produced an absorbance of 0.399 at a wavelength of 616 nm, using a cuvette with a pathlength of 1.000 cm. From the information provided, the molar absorptivity (in m2mol-1) of the solution is [[1]].
