- To calculate freezing point of a 1.7m aqueous ethylene glycol solution
Given:
Molaity(m) : 1.7m
Depression constant ;Kf(water): 1.860c/m
Formula for freezing point depression or freezing point
Tf = m 
Kf
Putting the values in formula:
Tf
= 1.7 m
1.86 0c/m = 3.2 0c
As
Tf negative value so we write
Tf as -3.2 0c
