1. What is Vapour Density at Equilibrium?

Definition: Equilibrium Vapour Density is the density of a vapour substance during the stages of reaction at equilibrium.

Purpose: This calculator helps determine the vapour density when the molecular weight at equilibrium is known.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ d = \frac{m_{ab}}{2} \]

Where:

Explanation: The abnormal molecular weight is divided by 2 to obtain the vapour density at equilibrium.

3. Importance of Vapour Density Calculation

Details: Understanding vapour density at equilibrium is crucial for chemical reaction studies, especially in determining molecular weights and reaction progress.

4. Using the Calculator

Tips: Enter the abnormal molecular weight in kilograms. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is abnormal molecular weight?
A: Abnormal molecular weight refers to the unusual mass of a substance during the equilibrium stage in a chemical reaction.

Q2: Why divide by 2 in the formula?
A: The division by 2 accounts for the relationship between vapour density and molecular weight in equilibrium conditions.

Q3: What units should I use?
A: The calculator uses kilograms for both input and output, but any consistent mass unit can be used as long as you're consistent.

Q4: Can this be used for any substance?
A: This formula is specifically for substances where the vapour density is half the abnormal molecular weight at equilibrium.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but actual experimental values may vary slightly due to real-world conditions.
