If the molar absorptivity constant for the red dye solution is 5.56×104 m-1cm-1, calculate the molarity of the red dye solution at the optimal wavelength 519nm and absorbance value 0.945
you may assume l = 1.20cm. hint: a=εlc
b. convert the molarity in part a to w/v%. show your work. molar mass of fd& c red #3 = 879.86g/mol refer to examples on next page
c. if you want to dilute the red dye solution in part a by 5 times in a single dilution step, explain in two sentences on how one should proceed with the dilution. in addition, calculate the final concentration of the diluted solution. show your work for the numerical part of this question.
