Worksheet: The Beer–Lambert Law
In this worksheet, we will practice calculating concentrations from UV–vis spectra, using calibration curves or molar extinction coefficients.
Which of the following is a false statement about molar absorptivity coefficients?
- AMolar absorptivities will be the same for each peak, regardless of wavelength, for a given molecule’s UV–vis spectrum.
- BMolar absorptivity coefficients for organic molecules are typically 10,000 M−1⋅cm−1.
- CMolar absorptivity coefficients are calculated based on absorbance and concentration.
- DMolar absorptivities can be used to compare the ability to absorb light at a given wavelength of different chromophores.
