1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_1 \) — Initial concentration (mg/mL)
• \( V_1 \) — Initial volume (mL)
• \( V_2 \) — Final volume (mL)
• \( C_2 \) — Final concentration (mg/mL)

Explanation: The formula shows that the final concentration is proportional to the ratio of initial volume to final volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial in laboratory work, pharmaceutical preparations, and chemical processing to achieve desired concentrations.

4. Using the Calculator

Tips: Enter all values in the appropriate units (mg/mL for concentrations, mL for volumes). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator be used for other concentration units?
A: Yes, as long as you maintain consistent units for C1 and C2 (e.g., both in μg/mL or both in g/L).

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The formula still works mathematically but may not represent a physical dilution process.

Q3: How precise should my measurements be?
A: Precision depends on your application. For critical applications, use more precise measuring equipment and more decimal places.

Q4: Does this account for density changes?
A: No, this assumes ideal behavior where volume changes are additive. For precise work with non-ideal solutions, more complex calculations may be needed.

Q5: Can I use this for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, you would need to perform multiple calculations or use a specialized serial dilution calculator.
