Question

If for a particular solution , deviation in freezing point is 0
73degre , Kf = 5 028K Kg/mol, what is the molaliy of the
solution

0 1452
23 76
132 6
0 8766

na · Accepted Answer

Depression in freezing point,

Î”TF=0 730C

Molal elevation constant,KF =5 028K kg/mol

Molality of the solution,m=?

According to the relation

Î”Tf=KF x m

m =0 73/5 028=0 1452 
molal

If for a particular solution , deviation in freezing point is 0.73degre , Kf = 5.028K Kg/mol, what is the molaliy of the solution. 0.1452 23.76 132.6 0.8766
