Answer: Concentration of the dye in solution is 1.159 M
Explanation:
According to Beer-Lambert law, the absorbance is directly proportional to the concentration of an absorbing species.
Formula used :
where,
A = absorbance of solution = 1.657
C = concentration of solution = ?
l = length of the cell = 0.701 cm
= molar absorptivity of this solution =
Thus the concentration of the dye in solution is 1.159 M
