Question 10
For a certain binary solution at constant
T and P
Vm=a1 +2 a2 m +3 a3 m2
Where m is the molality, a1, a2 and a3 are constant
and Vm is the partial molar volume. Deduce the
expression for the total volume VT as function of m
VT = 2 a2 m2 + a3 m3
T = a1 + a2 m2 +
m3
VT = 2a1 + 3 a3 m3
3
%3D
VT = a1 +2 a2 m2 + 3a3 m3
