Pretend you repeat the experiment using a different unknown chromium salt. The measured absorbance of solution "beta" is 0.65 AU. If the dilution factor between solution "alpha" and solution "beta" is 20x (twenty-fold), what's the concentration of chromium(VI) in solution "alpha"? Use this Beer's plot in your analysis:

Question
Pretend you repeat the experiment using a different unknown chromium salt.
The measured absorbance of solution "beta" is 0.65 AU. If the dilution factor
between solution "alpha" and solution "beta" is 20x (twenty-fold), what's the
concentration of chromium(VI) in solution "alpha"?
Use this Beer's plot in your analysis:
