1. What is the Dilution By Volume Formula?

The dilution by volume formula calculates the final concentration of a solution after dilution. It's based on the principle of conservation of mass, where 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 (mol/L)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)
• \( C_2 \) — Final concentration after dilution (mol/L)

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

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry labs, pharmaceutical preparations, and biological assays to achieve desired concentrations for experiments and applications.

4. Using the Calculator

Tips: Enter all values in consistent units (mol/L for concentration, liters for volume). All values must be positive numbers. The final volume (V2) must be greater than or equal to the initial volume (V1) for dilution.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for volume?
A: Yes, but all volumes must be in the same units (e.g., all in mL or all in L). The calculator currently expects liters.

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

Q3: Does this account for volume changes due to mixing?
A: No, this assumes ideal behavior where volumes are additive. For precise work, consider potential volume changes.

Q4: Can I use this for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, you would need to perform multiple calculations.

Q5: How precise should my measurements be?
A: Precision depends on your application. For most lab work, 4 significant figures is sufficient.
