Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 27 Sept. 2012 Jespersen, Brady, Hyslop Chapter 5B Molecular View of Reactions in Aqueous Solution Properties of Solutions: Quantitative Composition The molar concentration or molarity (M) is defined as: units of M = mol/L (mol L-1) Example: How many grams of AgNO3 are needed to prepare 250 mL of a 0.0125 M AgNO3 solution? NOTE: You can also solve this for concentration OR liters of solution CH. 5 Properties of Solutions: Quantitative Composition Solutions of high concentration can be diluted to make solutions of lower concentration. Dilution: CH. 5 Example: How much 1.0 M CuSO4 (aq) solution is required to prepare 250 mL of a 0.10 M CuSO4 (aq) solution? How much water is required? Solution Stoichiometry CH. 5

Florio 1 Conversion Factors Conversion Factor ? relates one quantity to another ? used to convert between two units in chemistry What is my height in centimeters (cm) if I am 5 feet 4 inches tall? 1. How many inches are in a foot? 2. How many inches are in a centimeter? 12 inches = 1 foot 1 inch = 2.54 cm Factor Label Method The factor-label method, or dimensional analysis lets us treat a numerical problem as one involving a conversion from one kind of units to another using conversion factors.

Florio 08 Dec. 2012 Jespersen, Brady, Hyslop Chapter 12.1-12.5 Intermolecular Attractions and the Properties of Liquids and Solids 1 Phases of Matter Intermolecular Interactions (interactions between molecules) determine the physical properties/states of matter . Important differences between gases, solids, and liquids: Gases Expand to fill their container Liquids Retain volume, but not shape Solids Retain volume and shape Types of Intermolecular Interactions Dipole-Dipole (including Hydrogen Bonding) Ion-Dipole Dispersion (Induced Dipole-Induced Dipole) Ion-Induced Dipole Intermolecular Interactions (interactions between molecules):
