Calculate the molar extinction coefficient of a solution containing 5 *10-4 g litre-1 of a biomolecule, molecular weight 275 g mol-1, and absorbance 0.75 in a 1.2 cm cuvette.
3202A 3.00 * 10-6M solution in a 1.0 cm cuvette read 16 % T at 620nm. What were the absorbance and the molar absorbancy index of the solution?
