1. What is the Dilution Formula?

The dilution formula calculates the final molarity of a solution after dilution, using the initial percent concentration, density, molecular weight, and volume changes. This is essential in chemistry and laboratory work for preparing solutions of specific concentrations.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( percent_{initial} \) — Initial percent concentration (%)
• \( density_{initial} \) — Initial density (g/mL)
• \( MW \) — Molecular weight (g/mol)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)

Explanation: The formula converts percent concentration to molarity and accounts for the dilution factor to determine the final concentration.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial for preparing solutions with precise concentrations in chemical experiments, medical laboratories, and industrial processes.

4. Using the Calculator

Tips: Enter all values in the specified units. Ensure all inputs are positive numbers. The calculator will compute the final molarity after dilution.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 10 in the formula?
A: The factor of 10 converts percent concentration (parts per hundred) to the appropriate units for molarity calculation.

Q2: Can I use different volume units?
A: The calculator uses liters (L) for volume. Convert other units to liters before input for accurate results.

Q3: What if my initial concentration is in different units?
A: Convert all concentrations to percent (%) before using the calculator for consistent results.

Q4: Is temperature considered in this calculation?
A: Temperature affects density. Use density values measured at the same temperature as your experiment for highest accuracy.

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