1. What is the Dilution Factor Formula?

The dilution factor formula calculates the final concentration of a solution after dilution. It's a fundamental calculation in chemistry and biology for preparing solutions of desired concentrations.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_{final} \) — Final concentration (M)
• \( C_{initial} \) — Initial concentration (M)
• \( DF \) — Dilution factor (dimensionless)

Explanation: The formula shows that the final concentration is inversely proportional to the dilution factor.

3. Importance of Concentration Calculation

Details: Accurate concentration calculation is crucial for preparing solutions in laboratory work, medical applications, and industrial processes.

4. Using the Calculator

Tips: Enter initial concentration in molarity (M) and dilution factor (must be ≥1). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical dilution factor range?
A: Common dilution factors range from 2 to 1000, but can be higher for highly concentrated stock solutions.

Q2: How do I calculate dilution factor from volumes?
A: DF = (final volume) / (initial volume). For example, adding 9mL solvent to 1mL solution gives DF=10.

Q3: Can I use this for serial dilutions?
A: For serial dilutions, multiply the individual dilution factors to get the total DF before using this calculator.

Q4: What units should I use?
A: The calculator uses molarity (M), but any consistent concentration units will work (mM, μM, etc.).

Q5: Does temperature affect the calculation?
A: The calculation itself is temperature-independent, but solution volumes may change with temperature.
