The Beer-Lambert Law is expressed as A=ϵbc. The symbol, c, refers toSelect one:capacitycohesioncatalystconcentration

Breaking Down the Problem

1. Identify the symbols in the Beer-Lambert Law: $A$, $\epsilon$, $b$, and $c$.
2. Determine what each symbol represents in the context of the law.

Relevant Concepts

• The Beer-Lambert Law is a fundamental principle in chemistry that relates the absorption of light to the properties of the material through which the light is traveling.

Analysis and Detail

• In the equation $A = \epsilon b c$:
  • $A$ is the absorbance (a measure of the amount of light absorbed).
  • $\epsilon$ is the molar absorptivity (extinction coefficient), which indicates how strongly the substance absorbs light at a particular wavelength.
  • $b$ is the path length through which the light travels (usually in centimeters).
  • $c$ is the concentration of the absorbing species in the solution (often in moles per liter).

Verify and Summarize

• The symbol $c$ specifically represents the concentration of the absorbing substance in the solution.

Final Answer

Thus, the correct answer is concentration.
