Stoichiometry Video: Grams to Moles
This problem demonstrates conversion from grams of one substance to moles of another substance within a chemical reaction. The problem comes from our Interactive Stoichiometry Practice Problem Set.
NOTE: I assume that you have the use of a periodic table. In working quantitative problems, I will usually round masses to the nearest gram. These examples demonstrate a considerable focus on the rules for simplifying fractions in order to work problems without a calculator.
