These videos follow along with the NMSI packet we received in class. They work through problems from the packet step-by-step. Feel free to fast forward and skip over parts you do not need top review.
The first video covers problems on Average Atomic Mass, Molar Conversions, Molar Mass, Mass Percent (% composition), and Determining Empirical and Molecular Formulas.
The second video covers problems on Balancing Equations, Reaction Stoichiometry, Limiting Reactants, and Percent Yield.
