(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

Change in T= imK

i=Van't Hoff factor

m=given

K=freezing point depression or boiling point elevation

3. 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
