1 M C6H1206s

1 M NaNO3

1 M Ca(NO3)2

1 M Li3PO4

Explanation:

Hope it helps!

The order of solutions from lowest freezing point to highest freezing point of the given compounds are Li₃PO₄ < Ca(NO₃)₂ < NaNO₃ < C₆H₁₂O₆.

How we calculate the depression in freezing point?

Depression in freezing point will be calculated from the following reaction as:

ΔTf = i × Kf × m, where

ΔTf = change in freezing point

i = Vant Hoff factor

Kf = freezing constant

m = concentration in terms of molality

In the question concentration of compounds are given in molarity and for all compounds it is same, so the depression in freezing point will directly depends on the Vant Hoff factors of given compounds.

  • Vant Hoff factor for NaNO₃ is 2.
  • Vant Hoff factor for Li₃PO₄ is 4.
  • Vant Hoff factor for Ca(NO₃)₂ is 3.
  • Vant Hoff factor for C₆H₁₂O₆(s) is 1.

From the above data it is clear that Li₃PO₄ will have the lowest freezing point and C₆H₁₂O₆ will have the highest and sequence from lowest to highest will be shown as:
Li₃PO₄ < Ca(NO₃)₂ < NaNO₃ < C₆H₁₂O₆.

Hence the required order is Li₃PO₄ < Ca(NO₃)₂ < NaNO₃ < C₆H₁₂O₆.
