A solution of ethanol (C2H5OH) in water is prepared by dissolving 75.0 mL of ethanol (density 0.79 g/cm3 ) in enough water to make 250.0 mL of solution. What is the molarity of the ethanol in this solution?
Chapter 10 - Liquids and Solids 10.1 Intermolecular Forces A. Dipole-Dipole Forces 1. Attraction between molecules with dipole moments a. Maximizes (+) ----- ( - ) interactions b. Minimizes (+) ----- ( + ) and (-) ----- ( - ) interactions 2. About 1% of strength of ionic bonds a. Unimportant in gas phase due to distance between molecules B. Hydrogen Bonding 1. Special dipole-dipole attraction a. Hydrogen covalently bonded to highly electronegative elements (N, O, F) has a higher than normal δ+ charge 2. Bond strength is higher than other dipole-dipole attractions 3. Important in the bonding of mole
