An unknown amount of a compound with a molecular mass of 264.37 g/mol is dissolved in a 10 mL volumetric flask. A 1.00 mL aliquot of this solution is transferred to a 25 mL volumetric flask, and enough water is added to dilute to the mark. The absorbance of this diluted solution at 327 nm is 0.487 in a 1.000 cm cuvette. The molar absorptivity for this compound at 327 nm is ϵ 327 = 6503 M^(−1) cm^(−1).
(a) What is the concentration of the compound in the cuvette?
(b) What is the concentration of the compound in the 10-mL flask?
(c) How many milligrams of the compound were used to make the 10-mL solution?
