The need arises in a laboratory for 2000 cm³ of an antifreeze solution consisting of
30 mol-% methanol in water. What volumes of pure methanol and of pure water at
25°C must be mixed to form the 2000 cm³ of antifreeze, also at 25°C? Partial molar vol-
umes for methanol and water in a 30 mol-% methanol solution and their pure-species
molar volumes, both at 25°C, are:
