1. What is the Ratio of Molecular Masses Calculator?

Definition: This calculator determines the ratio of molecular masses of two immiscible liquids (water and another liquid) based on their weights and vapor pressures.

Purpose: It helps chemists and chemical engineers analyze immiscible liquid mixtures and understand their properties.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \frac{M_A}{M_B} = \frac{W_{water} \times P_B°}{P°_{water} \times W_B} \]

Where:

\( M_A/M_B \) — Ratio of molecular masses (water to liquid B)
\( W_{water} \) — Weight of water in the mixture (kg)
\( P_B° \) — Vapor pressure of pure component B (Pa)
\( P°_{water} \) — Partial pressure of pure water (Pa)
\( W_B \) — Weight of liquid B in the mixture (kg)

Explanation: The formula relates the molecular masses of two immiscible liquids to their weights and vapor pressures in a mixture.

3. Importance of Molecular Mass Ratio Calculation

Details: Understanding this ratio helps in predicting distillation behavior, designing separation processes, and analyzing liquid-liquid systems.

4. Using the Calculator

Tips: Enter the weights of water and liquid B in kg, their respective vapor pressures in Pascals. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are immiscible liquids?
A: Immiscible liquids are those that don't mix to form a homogeneous solution (like oil and water).

Q2: Why is this ratio important?
A: It helps determine the composition of vapor above an immiscible liquid mixture.

Q3: What units should I use?
A: Use kilograms for weights and Pascals for vapor pressures for consistent results.

Q4: Can I use this for miscible liquids?
A: No, this formula is specifically for immiscible liquid systems.

Q5: How accurate is this calculation?
A: It provides theoretical values assuming ideal behavior and complete immiscibility.
