Скачать или смотреть Dimensional Analysis | Volume Displacement & Mercury Concentration (ppb) Problems

In this video, we apply dimensional analysis to solve common and meaningful problems involving volume conversions and trace pollutant analysis. These problems are excellent practice for chemistry students preparing for exams or learning how to apply chemistry to real-life situations.
In This Video:

✅ Dimensional Analysis Explained Step-by-Step
✅ Solving Real-World Problems Using Unit Conversions

✔ Problem 1: What is the displacement volume of an automobile engine, 161 in³, expressed in liters?

✔ Problem 2: The mercury content in a stream is analyzed to be 0.68 parts per billion (ppb) by weight.
Calculate how much mercury (in grams) is present in 15.0 L of water with a density of 0.998 g/mL.
(Conversion given: 1 ppb = 1 ng Hg / 1 g water)

Learn how to:
• Properly set up dimensional analysis problems
• Handle volume, mass, and trace contaminant conversions
• Avoid common mistakes when working with very small concentrations like ppb
• Relate chemistry calculations to environmental applications
