1. What is Molecular Mass of Liquid in Mixture of Two Immiscible Liquids?

Definition: This calculator determines the molecular mass of one liquid (A) in a mixture of two immiscible liquids based on their weights and vapor pressures.

Purpose: It's used in chemistry and chemical engineering to analyze properties of liquid mixtures that don't mix together (immiscible liquids).

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_A = \frac{W_A \times M_B \times P_B°}{P_A° \times W_B} \]

Where:

\( M_A \) — Molecular Mass of Liquid A (kg)
\( W_A \) — Weight of Liquid A (kg)
\( M_B \) — Molecular Mass of Liquid B (kg)
\( P_B° \) — Vapor Pressure of Pure Component B (Pa)
\( P_A° \) — Vapor Pressure of Pure Component A (Pa)
\( W_B \) — Weight of Liquid B (kg)

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

3. Importance of This Calculation

Details: Understanding molecular masses in immiscible liquid mixtures is crucial for distillation processes, phase equilibrium studies, and chemical separation techniques.

4. Using the Calculator

Tips: Enter all required values in consistent units (kg for masses, Pa for vapor pressures). Default values are provided as examples.

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 are vapor pressures important in this calculation?
A: The vapor pressures determine how each component contributes to the total vapor pressure of the mixture.

Q3: Can this formula be used for miscible liquids?
A: No, this specific formula applies only to immiscible liquid mixtures.

Q4: What if one of the weights is zero?
A: All weights must be greater than zero for the calculation to be valid.

Q5: How precise should my measurements be?
A: For accurate results, measure weights to at least 6 decimal places (microgram precision).
