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 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 (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 crucial in chemistry and biology for preparing solutions of precise concentrations, which is essential for experiments, medical tests, and industrial processes.

4. Using the Calculator

Tips: Enter all values in the specified units (concentration in mol/L, volumes in liters). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the molecular weight of water?
A: The molecular weight of water (H₂O) is approximately 18.015 g/mol.

Q2: Can I use this for other solvents besides water?
A: Yes, the dilution formula works for any solvent as long as the solute remains unchanged.

Q3: What if my volumes are in milliliters?
A: Convert to liters (1 L = 1000 mL) before using the calculator for accurate results.

Q4: Does temperature affect the calculation?
A: Temperature affects density but not molarity calculations unless there's significant volume change with temperature.

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