This study guide contains over 4 hours and 40 minutes of recorded lecture topics and example problems that follow the material covered in chapter 3 of the textbook Chemistry, The Molecular Nature of Matter and Change by Silberberg. The topics covered include: The mole concept and how it can be used. The relationship between molecular (formula) mass and molar mass. Comparison of- and conversions between the amounts of substances in moles, mass (grams), and number of chemical entities. The information provided by a chemical formula. The steps needed to find the empirical and molecular formulas of compounds. Different substances with the same empirical formula and those with same molecular formula (structural isomers). Balancing equations and their use in the quantitative variables of chemical reactions. The mole-mass-number relationships balanced chemical equations. How amounts of reactants and products are related. When one reactant limits how much product can be formed in a chemical reaction. The difference between theoretical and actual yields and how these are determined. The definitions of concentration and molarity. Definition of dilution and its effect on the concentration of solute.. Solution reactions and how differ from those of outside solution.
