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:

• \( \text{Initial Conc.} \) — Initial concentration in mol/L
• \( V1 \) — Initial volume in mL
• \( V2 \) — Final volume after dilution in mL

Explanation: The formula accounts for the proportional relationship between concentration and volume during dilution processes.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial for preparing solutions of desired concentrations in laboratories, pharmaceutical preparations, and various chemical processes.

4. Using the Calculator

Tips: Enter initial concentration in mol/L, initial volume (V1) in mL, and final volume (V2) in mL. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is molar mass considered indirectly?
A: Molar mass is incorporated through the concentration units (mol/L), which already account for the molecular weight of the solute.

Q2: Can this calculator handle different concentration units?
A: This calculator specifically uses mol/L for concentration. For other units, conversion to mol/L is required first.

Q3: What if V2 is smaller than V1?
A: V2 must be greater than V1 for proper dilution. If V2 < V1, it would represent concentration rather than dilution.

Q4: Are there limitations to this formula?
A: The formula assumes ideal mixing and that the solute doesn't undergo any chemical changes during dilution.

Q5: Can this be used for serial dilutions?
A: For serial dilutions, the calculation needs to be applied sequentially for each dilution step.
