Chapter 9.8, Problem 29P

Experimental data for the excess molar volume of 1-propanol (1) + 1-hexene (2) system at 298.15 K is provided in Table P9-29. If the pure component densities at 298.15 K are 0.79965 g/cm³ for 1-propanol and 0.66828 g/cm³ for 1-hexene, do the following.

1. A. Plot the solution molar volume as a function of composition of 1-propanol.
2. B. Fit the solution molar volume to an appropriate functional form.
3. C. Determine the partial molar volume for both substances when the system is equimolar.
