Problem 4. The table gives the experimental data of V^E for binary liquid mixtures of i and j at room temperature and I atm. (a) Determine from the data numerical

values of parameters a, b, and c in the correlating equation V^{E}=x_{1} x_{2}\left(a x_{1}^{2}+b x_{1}+c\right) (b) Generate the plot of V1^-E vs. X, based on the results of part a
