Asked by Carol Hamoonga
15. What volume of ethylene glycol (C2H6O2), a nonelectrolyte must be added to 15.0
L water to produce an antifreeze solution with a freezing point -25.5oC? What is the
boiling point of this solution? The density of ethylene glycol is 1.11 g/mL and the
density of water is 1.00 g/mL

The data for a freezing point of -25.3°C are
boil: 106.0°C
39.5% by volume (42% by weight)
so, using volume, you need x L of C2H6O2, where
x = 0.395(x+15)
x = 9.79L
you adjust for -25.5°C
