Instructional Ideas

  • Pause video to have viewers work out parts of the problem before watching solution
Classroom Considerations

  • Viewers need to have a good grasp of mass ratios and mole ratios
  • Example uses milligrams and millimoles; be sure learners know how to deal with these units

  • Video explains the process of finding empirical and molecular formulas step by step

  • Video quality is poor in some locations
  • At one point, speaker says hydrogen when he should have said sulfur
