1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It is 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 formula:

Where:

• \( M_2 \) — Final molarity (mol/L)
• \( M_1 \) — Initial molarity (mol/L)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume (L)

Explanation: The formula calculates the new concentration after diluting a solution from volume V1 to volume V2.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry laboratories for preparing solutions of specific concentrations, conducting experiments, and ensuring reproducible results.

4. Using the Calculator

Tips: Enter initial molarity in mol/L, initial volume in L, and final volume in L. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for volume?
A: The calculator uses liters (L) for volume. Make sure to convert milliliters or other units to liters before input.

Q2: Can I use this for serial dilutions?
A: This calculator calculates single-step dilutions. For serial dilutions, you would need to perform multiple calculations.

Q3: What if my final volume is less than initial volume?
A: The formula assumes V2 > V1 for dilution. If V2 < V1, you're concentrating the solution, not diluting it.

Q4: Does temperature affect the calculation?
A: The basic dilution formula assumes constant temperature and no volume contraction/expansion. For precise work, temperature effects may need consideration.

Q5: Can I use this for non-molar concentration units?
A: Yes, the formula works for any concentration unit (mol/L, g/L, etc.) as long as you're consistent with units.
