What is the freezing point depression of a 5.35 m aqueous solution of sucrose (a nonelectrolyte)? Show work and report answer with the correct units and number of significant figures.

This is a question on my homework and I'm completely lost... I don't know where to begin. I've been working on this too long now. Can anyone help?

Hi Calista,

To solve this problem, you should apply the equation for freezing point depression within the coligatives properties:

T2 - T1 : Kf * m 

where 

Kf : solvent constant (water = 1.85 K kg/mol ) 

m : molal concentration (mol/kg) 

and unit handling is on your own

I recommend to take  a look to
