K1: CHEMISTRY UNIT OUTLINE UNIT K: MATHEMATICS OF CHEMICAL EQUATIONS: STOICHIOMETRY TOPICS: OBJECTIVES: FRAMEWORK STRANDS: LEARNING STANDARDS: CLASSROOM HANDOUT MATERIALS This unit is designed to teach you how to: use the coefficients from balanced chemical equations to derive information regarding moles, particles, relative volumes, and formula masses; use the above information to solve quantitative problems regarding reactants and products. Upon completion of this unit, you will be expected to: 1. list what information can derived from the coefficients of a balanced equation (moles, molecules/particles, liters, etc.), 2. determine the reltive number of moles, molecules/particles, and liters represented by the coefficients of a balanced equation, 3. convert the number of moles of a substance into sample mass, 4. convert the number of moles of a substance into molecules/particles, 5. convert the number of moles of a substance into liters, 6. use stoichiometric analysis and dimensional analysis (factor label method) to solve problems involving the calculation of the mass, moles, particles and/or liters of a product given quantitative information about a reactant, 7. use stoichiometric analysis and dimensional analysis (factor label method) to solve problems involving the calculation of the mass, moles, particles and/or volume (in mL or L) of a product given quantitative information about a product.
