1. What is Weight of Water in Immiscible Mixture?

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

Purpose: It helps chemists and engineers calculate the required amount of water when working with immiscible liquid mixtures.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W_{water} = \frac{W_B \times P°_{water} \times M_{water}}{P°_B \times M_B} \]

Where:

\( W_{water} \) — Weight of water in the mixture (kg)
\( W_B \) — Weight of liquid B (kg)
\( P°_{water} \) — Partial pressure of pure water (Pa)
\( M_{water} \) — Molecular mass of water (0.018 kg/mol)
\( P°_B \) — Vapor pressure of pure component B (Pa)
\( M_B \) — Molecular mass of liquid B (kg/mol)

Explanation: The formula calculates the weight ratio of water to liquid B based on their vapor pressures and molecular weights.

3. Importance of This Calculation

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

4. Using the Calculator

Tips: Enter the weight of liquid B, partial pressure of water, vapor pressure of component B, and molecular mass of liquid B. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are immiscible liquids?
A: Liquids that don't mix together and form separate layers (like oil and water).

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

Q3: What's the molecular mass of water?
A: It's fixed at 0.018 kg/mol (18 g/mol) in this calculation.

Q4: Can I use different units?
A: Make sure all units are consistent (kg for weight, Pa for pressure, kg/mol for molecular mass).

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