complete the following table and calculate the decrease in the freezing point of water when 1 mol glycerol (CH3OH-CHOH-CH2OH), N

garik1379 [7]

The decrease in the freezing point of the solution is −1.86oC.

<h3>What is the decrease in the freezing point?</h3>

Now we know that the freezing point depression of a solid is a colligative property of the solution.

Thus we have that;

ΔT = K m i

ΔT = freezing point depression

K = freezing constant

m = molality of the solution

i = Van't Hoff factor

Thus;

molality = 1 mol/1 Kg = 1 m

ΔT = −1.86oC/m * 1 m * 1

ΔT =−1.86oC

igomit [66]

The periodic table arranges elements in increasing
atomic number from left to right and top to bottom.
Horizontal rows on the periodic table are periods.
Elements in the same period have the same number of
electron shells.
Vertical columns on the periodic table are groups.
Elements in the same group have the same number of
valence electrons.
