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:

• \( C_f \) — Final concentration (mg/L)
• \( C_i \) — Initial concentration (mg/L)
• \( V_i \) — Initial volume (L)
• \( V_f \) — Final volume (L)

Explanation: The formula calculates the final concentration by multiplying the initial concentration by the ratio of initial volume to final volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory settings, pharmaceutical preparations, chemical manufacturing, and environmental testing to achieve desired concentrations.

4. Using the Calculator

Tips: Enter initial concentration in mg/L, initial volume in liters, and final volume in liters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What if my volumes are in different units?
A: Ensure all volume units are consistent (all in liters or all in milliliters). Convert if necessary before calculation.

Q2: Can this formula be used for any concentration unit?
A: Yes, as long as the concentration units for C_i and C_f are the same (e.g., both mg/L or both μg/mL).

Q3: What is the dilution factor?
A: The dilution factor is V_f/V_i, which represents how many times the original solution was diluted.

Q4: How do I calculate the required dilution volume?
A: To find the volume of solvent needed, rearrange the formula: V_solvent = V_f - V_i.

Q5: Are there limitations to this formula?
A: This formula assumes ideal mixing conditions and that the solute doesn't react with the solvent or change properties during dilution.
