Final answer:
In chemistry, the difference between a plot of absorbance and concentration is that absorbance measures the amount of light absorbed by a substance, while concentration measures the amount of solute dissolved in a solvent.
Step-by-step explanation:
In chemistry, the difference between a plot of absorbance (abs) and concentration is that absorbance measures the amount of light absorbed by a substance, while concentration measures the amount of solute dissolved in a solvent.
Absorbance is directly proportional to concentration according to Beer-Lambert Law, which states that absorbance is equal to the product of molar absorptivity, path length, and concentration. On the other hand, the concentration can be determined by plotting a calibration curve of known concentrations and their corresponding absorbances.
