Dilution of a 0.005M standard solution of a compound is prepared by taking 2.00 mL of this solution and diluting with solvent to 25.00 mL. The diluted standard had an absorbance of 0.624 at 238 nm in a 1.00 cm cuvet. A blank solution containing only solvent had an absorbance of 0.029 at 238 nm. The absorbance of an unknown sample of this compound in the same solvent and cuvet had an absorbance of 0.377. • Calculate a) The concentration of the compound in this sample b) The molar absorptivity of this compound at 238 nm
