Question

Rearranging Beer's Law for Concentration

Original question: ϵ=AC×l\epsilon=\frac{A}{C\times l} where A is absorbance

Rearranging gives

C=Aϵ×lC=\frac{A}{\epsilon\times l}

FAQ

What is the Beer's Law equation?

ε = A / (C × l), where ε is molar absorptivity, A is absorbance, C is concentration, and l is path length.

How do you rearrange Beer's Law to find concentration?

C = A / (ε × l).
