Compound X was dissolved in a 5-mL volumetric flask. A 1.00-mL aliquot of the compound was placed in a 10-mL volumetric flask and diluted to the mark. The solution was read in a UV-Vis spectrophotometer and an absorbance of 0.427 in a 1.000-cm cuvette was observed at 340 nm. Solve the following question.   Data for Compound X: Molecular mass = 292.16 g/mol Molar absorptivity (ɛ) at 340 nm= 6130 M -1 cm -1 a. Calculate the concentration of compound X in the cuvette. b. How many milligrams of compound X were used to make the 5-mL solution?
