Explain the molar absorptivity for compound a

Reference no: EM13525898

You've been given a mixture of 2 compounds, A and B, which have been measured by spectrophotometry. The wavelength of maximum absorbance for compound A is 314.2nm (wavelength 1) and the wavelength of maximum absorbance for compound B is 264.8nm (wavelength 2).

The molar absorptivity for compound A is 739 at wavelength 1 and 461 at wavelength 2. The molar absorptivity for compound B is 319 at wavelength 1 and 266 aw wavelength 2.

Find the concentration (in molarity) for compounds A and B if the absorbance reading at wavelength 1 is .990 and the absorbance reading at wavelength 2=.562.
Assume a cell path length = 1.0
