Example Using Raoult's Law to Model Ternary VLE

In this example problem we apply Raoult's Law to model vapor/liquid equilibrium in a ternary system. As compared to a binary system, for a ternary system we are unable to solve our phase equilibrium relations (Raoult's Law) independent from our mass balance. If you are in my Fall 2023 Chemical Engineering Thermodynamics course, this corresponds to Problem 2 from Chapter 11. Below is a copy of the problem statement and my work (tablet), and my MATLAB M-files.
