• The Beer-Lambert law relates the absorption of light by a solution to three variables according to the equation

  • We can determine the concentration (molarity) of a sample by looking at the absorbance

Factors Affecting Calculations

  • Dilution (left water)→ measured absorbance is too low
  • Dirtiness (Ex: left fingerprints) or path of light is obstructed (ex: frosted wall)→ less light would pass thru solution and be detected = more light absorbed
