1. What is Dilution Factor?

The Dilution Factor (DF) is a dimensionless number that represents the ratio of the initial concentration to the final concentration in a dilution process. It indicates how many times a solution has been diluted.

2. How Does the Calculator Work?

The calculator uses the dilution factor formula:

Where:

• \( DF \) — Dilution Factor (dimensionless)
• \( C_i \) — Initial concentration (any units)
• \( C_f \) — Final concentration (same units as C_i)

Explanation: The formula calculates the factor by which a solution has been diluted by comparing the original concentration to the diluted concentration.

3. Importance of Dilution Factor Calculation

Details: Calculating dilution factor is essential in laboratory settings, pharmaceutical preparations, chemical manufacturing, and various scientific experiments where precise concentrations are required.

4. Using the Calculator

Tips: Enter both initial and final concentrations in the same units. Both values must be positive numbers, and the initial concentration must be greater than the final concentration.

5. Frequently Asked Questions (FAQ)

Q1: What does a dilution factor of 10 mean?
A: A dilution factor of 10 means the original solution has been diluted 10 times, making it 10 times less concentrated than the original.

Q2: Can dilution factor be less than 1?
A: No, dilution factor should always be greater than or equal to 1, as it represents the ratio of higher concentration to lower concentration.

Q3: How is dilution factor related to dilution ratio?
A: Dilution factor is the inverse of the dilution ratio. For example, a 1:10 dilution has a dilution factor of 10.

Q4: What units should I use for concentration?
A: You can use any concentration units (mg/mL, M, %, etc.) as long as both initial and final concentrations use the same units.

Q5: How do I calculate the volume needed for a specific dilution?
A: To achieve a specific dilution, use the formula: Volume of stock solution = (Final volume) / (Dilution factor)
