Chemistry: Percent Composition

The concept for this lesson is percentage composition. At this point in the year, students should have just finished a nomenclature unit, and feel comfortable writing and naming chemical formulas. They should be able to calculate molar mass, mole conversions, and use simple formulas. I teach this lesson after the nomenclature unit, and after a quick mole review lesson. I do like to challenge my honors and advanced honors students on this lesson—stretch the brain. Included, you will find ways to differentiate this lesson for standard and honors chemistry classes. Objectives: The student will calculate percent composition. Prior Knowledge for Students: Students should be comfortable with nomenclature, molar mass, and mole conversions prior to this lesson. Teacher Prep Time: Just print and go! Lesson Duration: One class period plus practice. Included in This Product: Editable, Animated PowerPoint (14 slides) Cornell Style Student Notes that
