PLEASE AND THANK YOU IN ADVANCE, will rate 5 stars and thumbs up plus recommend you! The spectrophotometer was used to measure the abosrbance of each of a series of [FeSal]+ solutions. A standard curve was constructed by plotting the absorbance vs. concentration (M). The slope and y-intercept were found to be 1493 M-1 and 0.005, respectively. An aspirin sample was prepared following the procedure given in the experiment. A 0.139 g sample of aspirin was hydrolyzed with 5 mL...
