Weight of Water Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: The formula calculates the weight ratio of water to liquid B based on their vapor pressures and molecular weights.
Details: Accurate calculation is essential for creating stable immiscible mixtures in chemical processes, extractions, and separations.
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.
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.
