Dilution Formula:
| From: | To: |
The molarity dilution formula calculates the final concentration of a solution after dilution. It is based on the principle that the number of moles of solute remains constant during the dilution process, expressed as \( M_f = M_i \times \frac{V_i}{V_f} \).
The calculator uses the dilution formula:
Where:
Explanation: The formula demonstrates that the final concentration is proportional to the initial concentration and the ratio of initial to final volumes.
Details: Accurate dilution calculations are essential in laboratory settings for preparing solutions of desired concentrations, pharmaceutical preparations, and various chemical experiments.
Tips: Enter initial molarity in M, initial volume in L, and final volume in L. All values must be positive numbers with initial and final volumes greater than zero.
Q1: What units should I use for the volumes?
A: The calculator uses liters (L) for volume units. Make sure to convert your measurements to liters if they are in different units.
Q2: Can this formula be used for any type of solution?
A: Yes, the dilution formula applies to all aqueous solutions where the solute concentration is expressed in molarity.
Q3: What if my final volume is less than initial volume?
A: The formula still works mathematically, but physically this would represent concentration rather than dilution, which may not be practical in most laboratory scenarios.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise. The practical accuracy depends on the precision of your measurements and equipment.
Q5: Can I use different concentration units?
A: This calculator is specifically designed for molarity. For other concentration units, different dilution formulas would be needed.
