1. What is a Dilution Calculator?

Definition: This calculator determines the final concentration of a solution after dilution, using the initial concentration and volumes.

Purpose: Essential for chemistry, biology, medicine, and any field requiring precise solution preparation through dilution.

2. How Does the Dilution Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_2 \) — Final concentration (units)
• \( C_1 \) — Initial concentration (units)
• \( V_1 \) — Initial volume (units)
• \( V_2 \) — Final volume after dilution (units)

Explanation: The formula maintains that the total amount of solute remains constant before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilutions are crucial for preparing correct concentrations in experiments, medical treatments, and industrial processes.

4. Using the Calculator

Tips: Enter the initial concentration, initial volume, and final volume after dilution. All values must be > 0. The units must be consistent for all inputs.

5. Frequently Asked Questions (FAQ)

Q1: What if my volumes are in different units?
A: Convert all volumes to the same unit before calculation (e.g., all in mL or all in L).

Q2: Can I use this for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, apply the formula sequentially for each step.

Q3: What concentration units can I use?
A: Any consistent units (mg/mL, M, %, etc.) as long as C₁ and C₂ use the same units.

Q4: How precise should my measurements be?
A: Use the same precision as your measuring equipment allows, typically 3-4 significant figures.

Q5: What's the difference between dilution and concentration?
A: Dilution reduces concentration by adding solvent, while concentration increases it by removing solvent.
