1. What is the Dilution Formula?

The dilution formula \( C_2 = C_1 \times \frac{V_1}{V_2} \) calculates the final concentration of a solution after dilution, where \( C_1 \) is the initial concentration, \( V_1 \) is the initial volume, and \( V_2 \) is the final volume after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_1 \) — Initial concentration (mg/mL)
• \( V_1 \) — Initial volume (mL)
• \( V_2 \) — Final volume after dilution (mL)
• \( C_2 \) — Final concentration (mg/mL)

Explanation: The formula shows that the final concentration is proportional to the ratio of initial volume to final volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, and chemical processing to achieve desired concentrations.

4. Using the Calculator

Tips: Enter all values in the specified units (mg/mL for concentrations, mL for volumes). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator be used for other concentration units?
A: Yes, as long as you maintain consistent units (e.g., μg/mL for both C1 and C2).

Q2: What if I need to calculate the volume needed for a specific dilution?
A: Rearrange the formula to solve for \( V_1 = \frac{C_2 \times V_2}{C_1} \).

Q3: Does this account for the volume of the solute?
A: No, this assumes ideal behavior where volumes are additive. For precise work, consider the solute's contribution to final volume.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but actual laboratory results may vary due to measurement errors or non-ideal solution behavior.

Q5: Can I use this for serial dilutions?
A: Yes, but you'll need to apply the formula sequentially for each dilution step.
