Question 7: (4 points) An unknown compound has molar absorptivity of 576 L.morcm at 325 nm. A 0.435 g of the pure compound was dissolved in water to make 100.0 mL of solution. A 10.0 mL aliquot of this solution was diluted to 100.0 mL in a volumetric flask. The diluted solution exhibited an absorbance of 0.475 at 325 nm in a 1.00 cm cell.
