### Quantifying moles, mass, entities or # of formula units, and Avagadro's number Lesson Plan

#### Content

mole, formula units, mass, molar mass, Avagadro's number, significant digits

#### Goals / Aims of The Lesson Plan

1. Students able to use formulas to calculate unknowns for the number of moles, mass, entities or formula units.

#### Objectives

1.Importance of the subject matter in relation to chemical processes.

2. Complete understanding of the subject.

3.Ability to problem solve in order to calculate unknowns.

#### Materials and Aids

periodic table, handouts, calculator, pencil

### Procedure

**A. Introduction-**

1. Provide background explanations of how important these concepts are
in the field of chemistry.

2. How the relationships between the moles and avagadro's number changed
the world of chemistry forever!

**B. Development-**

1. Demonstrate calculations on the white board by quantifying a mole and a formula mass unit. Also include Avagadro's Number.

**C. Practice-**

1. Students will complete a simple worksheet or class assignment that has them work out a formula mass of a compound. They can also work on a percentage composition problem.

**D. Independent Practice-**

1. Students will work out the formula mass for water, carbon dioxide, and sodium dioxide.

**E. Accommodations (Differentiated Instruction)-**

1. As needed mostly involves the use of extra time.

2. Full use of the Periodic table

3. A chemistry cheat sheet with important tools in order to complete tasks,
as a last resort.

**F. Checking for understanding-**

1. Teacher will travel around the room asking questions.

2. Teacher will also be marking worksheets as needed.

3. Reviewing what was learned in class at the conclusion.

**G. Closure-**

1. I will give the class a full review program to work out.
