You dissolve a compound with a molecular mass of 284.63 in a 10-mL volumetric flask. You remove a 1.00-mL aliquot, place it in a 25-mL volumetric flask and dilute it to the mark. The absorbance of this diluted solution at 345 nm was 0.451 in a 1.000-cm cuvet. The molar absorptivity for this compound at 345 nm is ?345 = 6185 M-1 cm-1.

(a) What is the concentration of the compound in the cuvet?

(b) What is the concentration of the compound in the 10-mL flask?
