Ethylene glycol, formula C2H6O2, is used as antifreeze for
automobiles and is sometimes mixed with water at a 1:1 ratio by
volume and produces a solution with a density of 1.07 g/mL. Assume
that the solution behaves ideally. Notes: at 25 oC the densities of
water and ethylene glycol are 1.00 g/mL and 1.11 g/mL,
respectively, the vapor pressures of water and ethylene glycol at
20 oC are 17.54 torr and 0.06 torr, respectively, and Kb and Kf of
water...
