Answer:
b. the absorbance is proportional to the concentration.
Explanation:
Beer's law states that the amount of energy absorbed or transmitted by a solution is proportional to the solution's molar absorptivity and the concentration of solute.
This means that concentrated solution absorbs more light than dilute solutions.
Going trough the options;
The correct option is option B. This is because as the concentration increases, the absorbance also increases. Hence absorbance is directly proportional to the concentration.
