CLAS Chem 1C Handout 6 Ch 17 Solutions (17.1-17.3) 1. An antifreeze solution is 25% ethylene glycol (C 2 H 6 O 2 ) by mass. The density of the solution is 1.05 g/mL. Calculate the molarity , molality and mole fraction of ethylene glycol. 2. 80 proof vodka is 40% ethanol (CH 3 CH 2 OH) by volume. The density of ethanol is 0.80 g/mL. Calculate the molality , molarity and mole fraction of ethanol in vodka. 3. What are the three “steps” for dissolving a solid solute in a liquid solvent to form a solution ? Can you predict ∆H and ∆S
