The concentration of a dilute aspirin solution is 0.000526 m. standard solutions of this compound were used to prepare a beer\'s
law plot which gives a slope of 1550.3 m-1. what is the expected absorbance value for the aspirin solution?
1 answer:
Answer:
0.815.
Explanation:
- We should mention Beer's law:
A = ∈bC.
Where, A is the absorbance of the solution.
b is the cell length of the cuvette.
C is the concentration of the solution.
- The calibration curve is a relation between A and C has a slope of (∈b).
We have C = 0.000526 M and a slope of (∈b) = 1550.3 M⁻¹.
∴ A = ∈bC = (1550.3 M⁻¹)(0.000526 M) = 0.815.
