Moles Lab Activities
Science Enhanced Scope and Sequence Chemistry Virginia Department of Education 2012 1 Moles Lab Activities Strand Molar Relationships Topic Investigating stoichiometry Primary SOL The student will investigate and understand that chemical quantities are based on molar relationships. Key concepts include a) Avogadro s principle and molar volume; b) stoichiometric relationships; c) solution concentrations; d) acid/base theory; strong electrolytes, weak electrolytes, and nonelectrolytes; dissociation and ionization; pH and pOH; and the titration process. Related SOL The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated produce observations and verifiable data.
Application: This activity should be used when introducing formulas of compounds, molecular masses, and percent composition. Helpful Hints/Suggestions: This activity is actually a set of four activities. Directions on the handouts have been intentionally kept short so students will focus on the concept rather than the directions.
