1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It is based on the principle that the amount of solute remains constant before and after dilution, while the volume changes.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

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

Explanation: The formula calculates how the concentration changes when a solution is diluted by adding more solvent while keeping the amount of solute constant.

3. Importance of Dilution Calculation

Details: Accurate dilution calculations are essential in laboratory settings, pharmaceutical preparations, and chemical experiments to achieve desired concentrations for various applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if I need to calculate the dilution factor?
A: The dilution factor is calculated as V_f/V_i. This represents how many times the original solution has been diluted.

Q2: Can this formula be used for other concentration units?
A: Yes, the formula works for any consistent concentration units (mg/L, μg/mL, etc.) as long as all units are the same.

Q3: What is the difference between dilution and concentration?
A: Dilution decreases concentration by adding solvent, while concentration increases the concentration by removing solvent or adding more solute.

Q4: How accurate are dilution calculations?
A: The calculations are mathematically precise, but practical accuracy depends on the precision of measurements and proper mixing techniques.

Q5: Can this calculator handle serial dilutions?
A: This calculator handles single dilutions. For serial dilutions, you would need to calculate each step sequentially.
