Unit 5 - Counting Particles Too Small to See Instructional goals
1. Use Avogadro's Hypothesis and experimental data to determine the relative mass of molecules.
2. Use
experimental data to determine the number of items in a sample without actually counting them.
3. Use
experimental data to determine the molar mass of elements.
4. Given the chemical formula of a substance,
determine the molar mass.
5. Given the mass of a substance, determine
a. the number of moles of the sample
b. the number of atoms or molecules in the sample
6. Given
the number of moles of a substance, find
a. the mass of the sample

7. Given the formula of
a compound, determine its % composition.
8. Given data about the % composition of a sample, determine
the empirical formula of the compound.
9. Given the empirical formula and information about the molar
mass of the compound, determine the molecular formula.
