Curriculum Expectations:
Overall Expectations:
D3. Demonstrate an understanding of the mole concept and its significance to that quantitative analysis of chemical reactions.
Specific Expectations:
D2.1 Use appropriate terminology related to quantities in chemical reactions, including, but not limited to: stoichiometry, percentage yield, limiting reagent, mole, and the atomic mass.
D2.2 Conduct an inquiry to calculate the percentage composition of a compound (e.g., a hydrate).
D2.4 Determine the empirical formulae and molecular formulae of various chemical compounds, given molar masses and percentage composition or mass data.
D3.3 Explain the relationship between the empirical formula and the molecular formula of a chemical compound.
