1. What is Ratio of Weights of Water to Liquid in Immiscible Mixture?

Definition: This calculator determines the ratio of weights of water to another immiscible liquid in a mixture based on their vapor pressures and molecular masses.

Purpose: It helps in distillation and separation processes where immiscible liquids are involved.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ WW:B = \frac{Powater \times Mwater}{PB° \times MB} \]

Where:

Explanation: The ratio is calculated by multiplying water's partial pressure with its molecular mass, divided by the product of component B's vapor pressure and molecular mass.

3. Importance of This Calculation

Details: This ratio is crucial in steam distillation processes where immiscible liquids are separated based on their vapor pressures.

4. Using the Calculator

Tips: Enter the partial pressure of water, molecular mass of water (default 0.018 kg), vapor pressure of component B, and molecular mass of component B. 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 (like oil and water).

Q2: Why is molecular mass of water fixed at 0.018 kg?
A: This is the standard molecular mass of water (18 g/mol converted to kg).

Q3: Where do I find vapor pressure values?
A: Vapor pressure values can be found in chemical engineering handbooks or material safety data sheets.

Q4: What units should be used?
A: Use Pascals for pressure and kilograms for molecular mass for consistent results.

Q5: Can this be used for miscible liquids?
A: No, this formula is specifically for immiscible liquid mixtures.
