Question
A 0.50 molal solution of ethylene glycol in water is used as coolant in a car. If the freezing point constant of water is 1.86o per molal, at which temperature will the mixture freeze ?
Options
A.1.56oC
B.- 0.93oC
C.- 1.86oC
D.0.93oC
Solution
ᐃTf = kf m.
ᐃTf = 1.86 × 0.5 = 0.93.
so Tf = - 0.93oC.
ᐃTf = 1.86 × 0.5 = 0.93.
so Tf = - 0.93oC.
