**Problem 1:**
Species A and B form a binary mixture that can be represented by Raoult’s Law.

1. **(i) If x<sub>A</sub> = 0.35 at T= 110°C, calculate the pressure and the vapor phase composition.**
2. **(ii) If y<sub>A</sub> = 0.35 at T= 110°C, calculate the pressure and the liquid phase composition.**
3. **(iii) What are the vapor and liquid phase compositions at T = 125°C and P = 175 kPa.**
4. **(iv) If the overall composition of species A (z<sub>A</sub>) is 0.50 at T= 125°C and P= 175 kPa, what fraction of the two-phase system is vapor?**

**Data:**
- At 110°C, P<sup>sat</sup><sub>A</sub> = 244.5 kPa and P<sup>sat</sup><sub>B</sub> = 54.3 kPa.
- At 125°C, P<sup>sat</sup><sub>A</sub> = 351.3 kPa and P<sup>sat</sup><sub>B</sub> = 84.1 kPa.

**Explanation:**
This problem involves calculations using Raoult’s Law, which is used to describe the vapor pressure of ideal mixtures. The given tasks require determining pressure and composition of phases under different conditions. The provided data includes the saturation pressures of species A and B at 110°C and 125°C. 

To solve these problems, we need to use the relationships defined by Raoult's Law, as well as principles of phase equilibrium for binary mixtures.
