binary mixture is given by the empirical expression:
ρ=a_0+a_1 x_1+a_2 x_1^2
find the corresponding expression for V ̅_1 and V ̅_2.
Summability
M=∑_ix_i M ̅_i (11.11)
M=x_1 M ̅_1+x_2 M ̅_2 (A)
dM=d(x_1 M ̅_1 )+d(x_2 M ̅_2 )
dM=x_1 dM ̅_1+M ̅

binary system in VLE at low Pressure, the equilibrium vapor-phase mole fraction y_1 corresponding to an equimolar liquid mixture is approximately
y_1=(P_1^sat)/(P_1^sat+P_2^sat )
where P_i^sat is a pure-species vapor pressure. Clearly, this equation is valid if Raoult’s law applies. Prove that
