Title: Liquid-Vapor Phase Diagram in Two-Component Systems Description: This video teaches how to solve problems using liquid-vapor phase diagrams in two-component systems to determine the number of moles of substances A and B in each phase. First, it describes the procedure for locating a point on the diagram, which represents the state of the system at a given temperature and mole fraction. To do this, establish the temperature T sub 1 and calculate the mole fraction of A from the number of moles given in the problem. The point found indicates that the system has two phases in equilibrium: liquid and vapor. The video shows how to obtain the mole fraction of A in both phases by reading the diagram and explains how to use a ruler to measure distances and calculate the measured fractions. To determine the amount of liquid and vapor in moles, the lever rule is used, which requires forming a system of equations along with a second equation derived from the total amount of matter in the system. Once the system is solved, the values for the moles of liquid and vapor are obtained. Finally, it explains how to calculate the number of moles of A and B in each phase from the mole fraction of A and the previous results, thus achieving the objective of the proposed problem.
