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?
To solve this problem, you should apply the equation for freezing point depression within the coligatives properties:
T2 - T1 : Kf * m
Kf : solvent constant (water = 1.85 K kg/mol )
m : molal concentration (mol/kg)
and unit handling is on your own
