Answer:
ΔTf = - 0.93 °C
Explanation:
We have molar solution value that is 0.50
Kf is the value of solvent constant that is the molal freezing point depression constant.
Kf = 1.86 °C/m for water
By using freezing point depression equation, we will find the freezing point
ΔTf = Kf · m
= -1.86 °C/m x 0.50 m
ΔTf = - 0.93 °C
