Chemistry

I. Grade Level/Unit Number: 9-12 Unit 7

II: Unit Title: Mole Concept

III. Unit Length: 7 days (on a 90 min. per day block schedule)

IV. Major Learning Outcomes:

Students should be able to: Mole Concept

• Calculate formula mass. • Convert representative particles to moles and moles to representative particles. (Representative particles are atoms, molecules, formula units, and ions.) • Convert mass of atoms, molecules, and compounds to moles and moles of atoms, molecules, and compounds to mass. • Convert representative particles to mass and mass to representative particles. • Convert moles to volume and volume to moles at STP. • Calculate molarity given mass of solute and volume of solution. • Calculate mass of solute needed to create a solution of a given molarity and volume • Solve dilution problems: M1V1 = M2V2. • Calculate empirical formula from mass or percent using experimental data. • Calculate molecular formula from empirical formula given molecular • Calculate molecular formula from empirical formula given molecular weight • Determine percentage composition by mass of a given compound • Perform calculations based on percent composition. • Calculate using hydrates.
