1. What is Weight of Liquid required to form Immiscible Mixture with Water?

Definition: This calculator determines the weight of liquid B needed to form an immiscible mixture with water based on their physical properties.

Purpose: It helps chemists and engineers calculate the required amount of a liquid to create a stable immiscible mixture with water.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W_B = \frac{W_{water} \times P_B° \times M_B}{P_{water} \times M_{water}} \]

Where:

\( W_B \) — Weight of liquid B (kg)
\( W_{water} \) — Weight of water in mixture (kg)
\( P_B° \) — Vapor pressure of pure component B (Pa)
\( M_B \) — Molecular mass of liquid B (kg)
\( P_{water} \) — Partial pressure of pure water (Pa)
\( M_{water} \) — Molecular mass of water (kg, default 0.018)

Explanation: The formula calculates the weight ratio based on the vapor pressures and molecular masses of the components.

3. Importance of This Calculation

Details: Accurate calculation is crucial for creating stable immiscible mixtures in chemical processes, extractions, and separations.

4. Using the Calculator

Tips: Enter the weight of water, vapor pressure of component B, its molecular mass, water's partial pressure, and water's molecular mass (default 0.018 kg). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is an immiscible mixture?
A: A mixture where two liquids don't dissolve in each other and form separate layers (like oil and water).

Q2: Why is vapor pressure important in this calculation?
A: Vapor pressure determines how the components distribute between the liquid and vapor phases.

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

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

Q5: Why is water's molecular mass fixed at 0.018 kg?
A: This is the standard molecular mass of water (18 g/mol converted to kg).
