The volume of a binary mixture has been reported in the following polynomial form: 

a. What values should be used for b₁ and b₂?

b. Derive, from the equation here, expressions for V̅₁,

c. Derive, from the equation here, expressions for the partial molar excess volumes of each species at infinite dilution, that is, V̅^ex₁ (T, P, x₁ → 0) and V̅^ex₂ (T, P, x₂ → 0).
