Weight of Liquid B Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: The formula calculates the weight ratio based on the vapor pressures and molecular masses of the components.
Details: Accurate calculation is crucial for creating stable immiscible mixtures in chemical processes, extractions, and separations.
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.
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).
