Unit 6: The Mole and Stoichiometry

In this unit, students learn the mathematical tool of dimensional analysis, alternately called the factor-label method. Students also explore how to predict and measure the outcome of a reaction.

Start Unit

7 Segments in this Unit

Stoichiometry is introduced in this segment.

Segment A: Dimensional Analysis

Stoichiometry is introduced in this segment, and the students discuss the basics of dimensional analysis.

This segment examines the mole and Avogadro's number.

Segment B: The Mole

This segment examines the mole and Avagadro's number. The students continue their exploration of dimensional analysis.

The topics of this segment include converting moles to liters.

Segment C: Percent Composition and Empirical Formulas

The topics found within this segment include converting moles to liters as well as calculating percent composition, empirical formulas, and molecular formulas.

This segment explores stoichiometric calculations and mole ratios.

Segment D: Stoichiometric Calculations

This segment explores stoichiometric calculations and mole ratios.

The students perform a lab demonstrating a limiting reactant problem.

Segment E: Limiting Reactants

This segment explores limiting reactants as we watch the students perform a lab with s'mores.

In this segment, the students discuss the ratios.

Segment F: Combustion Lab

In this segment, the students discuss the ratios they have calculated in a rocket combustion lab.

The students perform a rocket combustion lab in this segment.

Segment G: Combustion Lab Results

The students analyze data from the rocket combustion lab started in the previous segment and hear from special guest Dr. David Gottfried about nanotechnology.
