Consider a binary mixture of components A and B at temperature T and pressure P.
Let V̄A and V̄B be the partial molar volumes of A and B, respectively.
At a certain mole fraction of A, xA,
(∂V̄A / ∂xA)T,P = 22 cm3 mol−1
and
(∂V̄B / ∂xA)T,P = −18 cm3 mol−1 The value of xA, rounded off to 2 decimal places, is __________
and
(∂V̄B / ∂xA)T,P = −18 cm3 mol−1 The value of xA, rounded off to 2 decimal places, is __________
Correct : 0.45
