 |
Remember: Any schedule changes are made to the Calendar, not this page!
Goal: To develop the concept of the mole as a useful measurement and to apply this in calculations involving mass and volume.
Objectives: The student should be able to:
1. Define the mole in terms of Avogadro's number, formula mass or molecular mass.
2. Given the number of moles, determine the number of molecules of a covalent compound, formula units of an ionic compound or atoms of an element.
3. Given the number of particles present in a sample, determine the number of moles.
4. When given the formula, calculate the molecular mass of a covalent compound or the formula mass of an ionic compound.
5. Given the number of moles in a substance, determine the mass of the substance.
6. Given the mass of a substance, determine the number of moles of the substance.
7. When given the formula, calculate the percentage composition of each of the elements in the compound.
8. Given masses of the constituents or percentage composition data, determine the empirical formula of a compound.
9. Determine the molecular formula when the empirical formula is given or can be calculated and the molecular mass is given.
10. When given the formula or experimental data, calculate the percentage water in a hydrated compound.
11. Determine the empirical formula of a hydrated compound when given the percentage composition or the masses of the anhydrous substance and the water present.
