What is the molal concentration of a sucrose (C12H22011) solution whose freezing point is -2.00 °C? The Kf for water is 1.86 °C/m.

The molal concentration of sucrose solution is 1.07 m

Explanation:

Depression in freezing point is given by:

= Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte such as sucrose)

= freezing point constant =

m= molality

Putting in the values:

Thus molal concentration of sucrose solution is 1.07 m

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
