An unknown amount of a compound with a molecular mass of 274.12 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 329 nm is 0.579 in a 1.000 cm cuvette. The molar absorptivity for this compound at 329 nm is €329 = 6459 M-'cm!. What is the concentration of the compound in the cuvette? concentration: M What is the concentration of the compound in the 10 ml flask? concentration: M How many milligrams of compound were used to make the 10 mL solution? mass: mg
