Answer:
Concentration of the solution is 0.376M
Explanation:
Lambert-Beer's law describes the absorbance of a solution that is directely proportional to concentration of the solution, molar absorptivity and path length. The law is:
A = ε×C×l
Where A is absorbance (0.699 for Red Dye #3), ε is molar absorptivity (1.217L mol⁻¹cm⁻¹), C is concentration of solution and l is path length (1.526cm)
Replacing:
0.699 = 1.217L mol⁻¹cm⁻¹×C×1.526cm
C = 0.3764 mol/L
Concentration of the solution is 0.376M
