SUMMARY

The Beer-Lambert law is applied in this discussion to determine the concentration of a solution. The user calculated absorbance (A) using the formula A = log(io/I) and derived a concentration of approximately 20mM. However, the correct concentration is stated as 2mM, indicating a miscalculation in the application of the Beer-Lambert law. The discrepancy arises from the incorrect interpretation of the logarithmic values or the initial parameters used in the calculation.

PREREQUISITES
  • Understanding of the Beer-Lambert law
  • Familiarity with logarithmic functions
  • Basic knowledge of absorbance and transmittance in spectroscopy
  • Experience with concentration calculations in chemistry
NEXT STEPS
  • Review the Beer-Lambert law and its applications in analytical chemistry
  • Study logarithmic calculations and their implications in scientific formulas
  • Explore common mistakes in concentration calculations in spectroscopy
  • Learn about the significance of units in concentration measurements
USEFUL FOR

Chemistry students, laboratory technicians, and professionals involved in analytical chemistry who seek to understand the Beer-Lambert law and improve their calculation accuracy.

Homework Statement
Light intensity decreases by a factor of 100 when light passes through a 1cm cuvette with solution. Molar extinction coefficient is 105M-1cm-1. Find concentration.
Relevant Equations
A=ECL
A = log(io/I)
A=ECL
A = log(io/I)
A = log100/1 = 2

2/105M(1cm) = 0.019M ~ 20mM

Apparently the answer is 2mM, where did I go wrong?
