1. What is the Dilution Formula?

The dilution formula \( C_2 = C_1 \times \frac{V_1}{V_2} \) calculates the final concentration of a solution after dilution, where C1 is the initial concentration, V1 is the initial volume, and V2 is the final volume after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

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

Explanation: The formula maintains the conservation of mass principle, where the amount of solute remains constant before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and various industries for preparing solutions of precise concentrations.

4. Using the Calculator

Tips: Enter all values in the correct units (mol/L for concentration, liters for volume). Ensure all values are positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different volume units?
A: Yes, but all volumes must be in the same unit (convert mL to L by dividing by 1000 if needed).

Q2: What if my final volume is less than initial volume?
A: That would represent concentration, not dilution. This calculator is for dilution calculations only.

Q3: How precise should my measurements be?
A: For laboratory work, use at least 4 decimal places. For educational purposes, 2-3 decimal places are usually sufficient.

Q4: Does this work for percent solutions?
A: Yes, if you maintain consistent units (e.g., % w/v to % w/v). For converting between molarity and percent, additional information is needed.

Q5: Can I dilute multiple times?
A: Yes, you can perform serial dilutions by applying the formula sequentially for each dilution step.
