Transcribed Image Text:2. In a laboratory experiment, the freezing point of an aqueous solu-
tion of glucose is found to be –0.325°C. What is the molal concen-
tration of this solution?
Expert Solution
Step 1
∆Tf = i × kf × m
where ;
∆Tf is freezing point depression
i is van't hoff factor
Kf is freezing point depression constant
m is the molal concentration
