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, only the volume changes.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_1 \) — Initial concentration (g/L)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)
• \( C_2 \) — Final concentration (g/L)

Explanation: The formula maintains mass balance - the total amount of solute remains the same before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and many industrial processes where precise concentrations are required.

4. Using the Calculator

Tips: Enter all values in consistent units (g/L for concentration, L for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units?
A: Yes, as long as you're consistent (e.g., mg/mL for all concentration terms and mL for all volume terms).

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution, and isn't physically meaningful in this context.

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

Q4: Does this work for molar concentrations?
A: Yes, the formula works for any concentration units as long as C₁ and C₂ are in the same units.

Q5: What about serial dilutions?
A: For serial dilutions, apply the formula sequentially for each dilution step.
