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 :
[tex]A=\epsilon \times C\times l[/tex]
where,
A = absorbance of solution = 1.657
C = concentration of solution = ?
l = length of the cell = 0.701 cm
[tex]\epsilon[/tex] = molar absorptivity of this solution =
[tex]1.657=2.038Lmol^{-1}cm^{-1}\times C\times 0.701cm[/tex]
[tex]C=1.159mol/L[/tex]
Thus the concentration of the dye in solution is 1.159 M
Concentration of the dye in solution is 1.159 M
Beer-Lambert Law:
According to Beer-Lambert law, the absorbance is directly proportional to the concentration of an absorbing species. The concentration can be calculated by using this law which is given as:
[tex]A=E*l*c[/tex]
where,
A = absorbance of solution = 1.657
c = concentration of solution = ?
l = length of the cell = 0.701 cm
E= molar absorptivity of this solution = [tex]2.038 L mol^{-1} cm^{-1}[/tex]
On substituting the values:
[tex]A=E*l*c\\\\1.657=2.038*0.701*c\\\\c=\frac{1.657}{2.038*0.701}\\\\ c=1.159mol/L[/tex]
Thus, the concentration of the dye in solution is 1.159 M.
