1. What is the Dilution Formula?

The dilution formula \( M_f = M_i \times \frac{V_i}{V_f} \) calculates the final molarity after dilution, where a solution is mixed with additional solvent to increase its volume while decreasing its concentration.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( M_f \) — Final molarity (mol/L)
• \( M_i \) — Initial molarity (mol/L)
• \( V_i \) — Initial volume (L)
• \( V_f \) — Final volume (L)

Explanation: The formula maintains the conservation of moles principle, where the number of moles remains constant before and after dilution.

3. Importance of Dilution Calculation

Details: Accurate dilution calculations are essential in physiology and biochemistry for preparing solutions of specific concentrations, conducting experiments, and administering medications.

4. Using the Calculator

Tips: Enter initial molarity in mol/L, initial volume in liters, and final volume in liters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the dilution formula important in physiology?
A: It helps in preparing solutions with precise concentrations needed for various physiological experiments and medical applications.

Q2: Can this formula be used for any type of solution?
A: Yes, the dilution formula applies to any solution where the solute is uniformly distributed and doesn't react with the solvent.

Q3: What units should I use for volume?
A: While liters are standard, any consistent volume unit can be used as long as both Vi and Vf are in the same units.

Q4: What if my final volume is less than initial volume?
A: The formula still works mathematically, but practically this would represent concentration rather than dilution.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but practical accuracy depends on the precision of your measurements and equipment.
