1. What is the Ratio of Molecular Masses of 2 Immiscible Liquids?

Definition: This calculator determines the ratio of molecular masses of two immiscible liquids in a mixture based on their vapor pressures and weights.

Purpose: It helps chemists and chemical engineers understand the composition of immiscible liquid mixtures, particularly in distillation processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M_{A:B} \) — Ratio of molecular masses of liquid A to liquid B
• \( P_B° \) — Vapor pressure of pure component B (Pascal)
• \( W_A \) — Weight of liquid A (kg)
• \( P_A° \) — Vapor pressure of pure component A (Pascal)
• \( W_B \) — Weight of liquid B (kg)

Explanation: The ratio is derived from the relationship between the vapor pressures and weights of the two immiscible liquids in the mixture.

3. Importance of Molecular Mass Ratio Calculation

Details: Understanding this ratio is crucial for designing separation processes, predicting boiling points, and analyzing the behavior of immiscible liquid mixtures.

4. Using the Calculator

Tips: Enter the vapor pressures of both pure components (in Pascal) and the weights of both liquids (in kg). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are immiscible liquids?
A: Immiscible liquids are liquids that don't mix with each other and form separate layers, like oil and water.

Q2: How do I measure vapor pressure?
A: Vapor pressure can be measured experimentally or found in chemical reference tables for pure substances.

Q3: What units should I use?
A: Use Pascals for vapor pressure and kilograms for weights. Make sure all units are consistent.

Q4: Can this be used for miscible liquids?
A: No, this formula specifically applies to immiscible liquid mixtures.

Q5: What does the ratio tell us?
A: The ratio indicates the relative molecular masses of the two components in the immiscible mixture.
