A solution of a compound with a known extinction coefficient of 23,100 M-1cm-1 has an absorbance of 0.735 in a 1.30cm path length, what is the concentration of the solution

2.448 * 10^-5M

Explanation:

To calculate the concentration of the solution, we apply the Beer Lambert law equation.

That is A = £LC

Where £ represents the molar extinction coefficient.

We identify the values as follows:

A = absorbance = 0.735

L = cell length = 1.30

£ = 23100

c = concentration = ?

Rearranging the equation, c = A/£L

c = 0.735/(23,100 * 1.3)

c = 2.448 * 10^-5 M
