2457.6
Explanation:
I calculated the answer and got it right.
Answer:
Answer has been given below.
Explanation:
- According to Beer's law-
- represents molar absorptivity of a solution, c represents molarity of solution and l represents cell thickness.
- Measurement of absorption is done by taking solutions of a particular solute with different concentrations. A particular solute has a particular maximum absorption wavelength. So absorption experiment is done by keeping this maximum absorption wavelength constant.
- remains constant for a particular solute and a particular absorption wavelength.
- During absorption experiment, same cuvette with a particular cell thickness is used. So "l" remains constant during experiment.
- So the variables are "c" and "A" as absorption depends on concentration of solution.
- Therefore Beer's law can be considered as y=mx relation, where y is equivalent to "A" , x is equivalent to "c" and m is equivalent to "".
- Now, y=mx represents a straight line passing through origin. Therefore y-intercept of any Beer's law plot equal to zero.
