Total amount of dye obtained (crystal violet) = 6.5mL
The absorbance using UV spectrometer is =1.75

Please help within the following

Using the reported value of the extinction coefficient of 112,000 M^-1 cm^-1, calculate the concentration of diluted sample and (according for dilution ) estimate the percent yield of this reaction by determining the number of moles of the dye formed. You can assume that the dye follows the Beer-Lambert Law and that A=ebc which for a 1cm cell simplifies to Absorbance A= ( 112,000 M^-1 cm^-1)(1.00cm) (concentration of crystal violet).

Please help thank you!
