All Chapters Video 0.8 Beer-Lambert Law Chapter OutlineChapter Quiz Question? Ask Dr. Mike! Lesson Summary Absorbance = εcl ε = molar extinction coefficient (molar absorptivity) Note: Things that are brightly-colored have higher ε values c = sample’s concentration l = path length (distance between the light source and the detector in a spectrophotometer) Hint: If you know the absorbance of a solution, you can calculate its concentration Lesson 0.8 Beer-Lambert Law 0.1 Atoms, Ions, and Molecules 0.1 Quiz Video Solution 0.2 Naming Ionic Compounds 0.2 Quiz Video Solution Pt. 1 0.2 Quiz Video Solution Pt. 2 0.3 Naming Molecular Compounds and Acids 0.3 Quiz Video Solution 0.4 Metric Units and Dimensional Analysis 0.4 Quiz Video Solution Pt. 1 0.4 Quiz Video Solution Pt. 2 0.4 Quiz Video Solution Pt. 3 0.5 Significant Figures and Percent Error 0.5 Quiz Video Solution 0.6 Lab Safety 0.7 Weights, Measures, and pH 0.8 Beer-Lambert Law Instructor Dr. Mike Christiansen Dr. Christiansen is a chemistry professor at Utah State University and has a PhD in organic chemistry.
