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.
The answer to question #19 is C-12, the reference isotope for atomic masses. Moles Lab Activity 2: Elements Time: Students will need about 5–10 minutes at each lab station to do initial calculations and measurements. They will need a total of 15–20 minutes to complete all questions, some of which could be completed at home.
