Guided Notes
Key concepts students will learn:
- •
When converting from grams to moles or vice versa, we use molar mass as a conversion factor.
- •
A mole ratio, which is found in the balanced equation, is used when you are changing your compound.
- •
When you see the keywords atoms, molecules, particles, or formula units, you should use Avogadro's number as a conversion factor.
