A never circulated 1975 penny with a mass of 3.00 g was dissolved in concentrated nitric acid, the resulting solution was then diluted to 50.0 mL with water. The weight percent copper in the penny was determined to be 94.7%. If the best-fit line for the Beer’s law plot was y=1.5x + 0.02, what is the absorbance of the penny solution?
