Homework Statement
Calculate the freezing point and boiling point of each of the following solutions using the observed van't Hoff factors in Table 11.6.
(a) 0.070 m MgCl2
Temp Freezing?
Temp Boiling?
(b) 0.020 m FeCl3
Temp Freezing?
Temp Boiling?
Homework Equations
Change in T= imK
i=Van't Hoff factor
m=given
K=freezing point depression or boiling point elevation
The Attempt at a Solution
I don't know what the change in temp is so I can't solve for K.
Tf MgCl2- Change in T= (3)(.07)K Don't know K or T
