Get Focused
Predicting the chemical yields of chemical reactions requires a knowledge of the mole and molar ratio's. In this lesson we will review the concept of the mole and learn how to use molar ratios to predict chemical yields.
Consider the following essential questions as you complete Lesson 1:
- What is a mole ?
- What is a molar ratio ?
- What is a limiting reagent ?
- How do we calculate percent yield
