1. What is the Dilution Formula?

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

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( Final \) — Final concentration (mg/mL)
• \( initial \) — Initial concentration (mg/mL)
• \( V1 \) — Volume of initial solution used (mL)
• \( V2 \) — Total volume after dilution (mL)

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

3. Importance of Dilution Calculations

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

4. Using the Calculator

Tips: Enter all values in positive numbers. V2 must be greater than or equal to V1. Results are rounded to 4 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: What if V2 is less than V1?
A: This would represent concentration rather than dilution and is not calculated by this tool. V2 must be ≥ V1 for dilution calculations.

Q2: Can I use different concentration units?
A: This calculator specifically works with mg/mL. For other units, convert all values to consistent units before calculation.

Q3: How precise should my measurements be?
A: For critical applications, measure volumes with precision glassware and concentrations with analytical instruments.

Q4: Does temperature affect dilution calculations?
A: Temperature affects solution density but not the mass-based calculation shown here, assuming proper mixing.

Q5: Can this be used for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, apply the formula sequentially for each step.
