1. What is the Dilution Formula?

The dilution formula \( C2 = \frac{C1 \times V1}{V2} \) calculates the final concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C1 \) — Initial concentration (mg/mL)
• \( V1 \) — Initial volume (mL)
• \( V2 \) — Final volume (mL)
• \( C2 \) — Final concentration (mg/mL)

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

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory settings, pharmaceutical preparations, chemical manufacturing, and medical treatments 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 units should I use for this calculator?
A: This calculator is designed for mg/mL concentrations and mL volumes. Ensure all inputs use consistent units.

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

Q3: What if I need to calculate a different variable?
A: The formula can be rearranged to solve for any variable: \( C1 = \frac{C2 \times V2}{V1} \), \( V1 = \frac{C2 \times V2}{C1} \), or \( V2 = \frac{C1 \times V1}{C2} \).

Q4: Are there any limitations to this formula?
A: This formula assumes complete mixing and no chemical reactions between solute and solvent. It may not account for volume changes due to molecular interactions.

Q5: How precise should my measurements be?
A: The precision depends on your application. For critical applications, use high-precision measuring instruments and consider significant figures in your calculations.
