To find the concentration of the compound, we can use the Beer-Lambert Law, which relates the absorbance of a solution to the concentration and molar absorptivity of the compound.
The Beer-Lambert Law equation is:
A = ε * c * l
Where:
A is the absorbance,
ε is the molar absorptivity (in units of M^-1 cm^-1),
c is the concentration (in units of M),
l is the path length (in units of cm).
Given values:
Absorbance (A) = 0.52
Molar absorptivity (ε) = 12,600 M^-1 cm^-1
Path length (l) = 1 cm
Substituting the given values into the equation, we get:
0.52 = 12,600 * c * 1
Simplifying the equation:
0.52 = 12,600 * c
Now, we can solve for the concentration (c):
c = 0.52 / 12,600
Calculating the concentration:
c = 0.00004127 M
Therefore, the concentration of the compound in the solution is approximately 0.00004127 M.
