Product description
- A 0.0325 g sample of p-nitroaniline was dissolved in methanol in a 50.0 ml volumetric flask. An aliquot of the resulting solution was placed in a 50.0 ml volumetric flask. A 1.00 ml aliquot of the resulting solution was diluted with methanol in a 100.0 ml volumetric flask. The optical density of this solution at λ = 368 nm in a cell with l = 1.00 cm is 0.802. Calculate the molar absorption coefficient (ε) of nitroaniline in methanol at the specified wavelength. The molecular weight of (C6H6N2O2) is 138.1.
