1. What is the Ratio of Weights of 2 Immiscible Liquids?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W_{A:B} = \frac{P_A° \times M_A}{P_B° \times M_B} \]

Where:

\( W_{A:B} \) — Weight ratio of liquid A to liquid B
\( P_A° \) — Vapor pressure of pure component A (Pascal)
\( M_A \) — Molecular mass of liquid A (kg)
\( P_B° \) — Vapor pressure of pure component B (Pascal)
\( M_B \) — Molecular mass of liquid B (kg)

Explanation: The ratio is determined by the product of each component's vapor pressure and molecular mass.

3. Importance of Weight Ratio Calculation

Details: Knowing the weight ratio helps predict the behavior of immiscible liquid mixtures during distillation and separation processes.

4. Using the Calculator

Tips: Enter the vapor pressures and molecular masses for both components. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are immiscible liquids?
A: Liquids that don't mix to form a homogeneous solution (e.g., oil and water).

Q2: Why is vapor pressure important in this calculation?
A: Vapor pressure determines how much each component contributes to the vapor phase.

Q3: What units should I use for molecular mass?
A: Use kilograms (kg) for consistency with SI units.

Q4: Can this be used for more than two components?
A: No, this formula is specifically for binary mixtures of immiscible liquids.

Q5: What if my liquids are partially miscible?
A: This formula works best for completely immiscible liquids. Partial miscibility requires more complex calculations.
