The concentration of phenol in an aqueous solution is 10 ug/mL. The absorbance is found to be 0.209 when this solution is placed in a 1.00 cm cuvette and 258 nm radiation is passed through Calculate the specific absorptivity, including units, of phenol? What will be the absorbance if the solution is diluted to 5 ug/mL? What will be the absorbance if the path length of the original solution is increased to 5.00 cm?
