1 Consider the total volume of a binary mixture of components A and B given by the polynomial fit v=987.93+35.4774x0.45923x2+0.017325x3 where v=V/cm3,x=n/mol, and nB is the amount of B in the mixture. i) Derive in clear steps an expression for the partial molar volume of B. [5] ii) Calculate the partial molar volume of B at ng=0.1534mol. [2]
