a) Determine the concentration of your prepared Iron (III) Salicylate Dianion solution (pure ASA) in the 10.0. mL of 1.0 M NaOH in mg/mL (Part D) using the Beer's Law plot completed in Question 1. Hint: You need to use the measured absorbance reading of your prepared Iron (III) dianion. b) Then, calculate the mass (in mg ) of pure ASA knowing that two consecutive dilutions were done to prepare the solution. Show all of your work. given information: beer's law Standard: Concentration of ASA in Standards (mg/mL) A: 0.18 B: 0.14 C: 0.10 D: 0.070 E: 0.040 Sample: Absorbance reading standard A: 1.25 standard B: 0.96 standard C: 0.74 standard D: 0.50 standard E: 0.23 the absorbance reading for my prepared iron (III) dianion is 0.83 the volume is 25.0mL b is the path length of the cuvette (assume 1 cm) the molecular weight of Iron (III) Salicylate Dianion is 330.09g/mol (correct me if i am wrong) i do not have the molar absorptivity, but the equation is 7,1*x +0.017 for the slope-intercept form of the best fit line.
