Boiling point of a solution given density and molecular weight
An environmentally concerned graduate student uses the more earth-friendly anti-freeze, propylene glycol (C3H8O2, density = 1.038). The final composition in her car's radiator is 30% (volume/volume) ethylene glycol (C2H6O2, density 1.114 g/ml)
and 20% (V/V) propylene glycol in water. At what temperature will her engine overheat? (Kb for water =0.52)
