Dilution Formula:
| From: | To: |
The dilution formula calculates the final percentage concentration after diluting a solution. It's based on the principle that the amount of solute remains constant during dilution, while the total volume increases.
The calculator uses the dilution formula:
Where:
Explanation: The formula maintains the conservation of mass principle, where the amount of solute remains constant before and after dilution.
Details: Accurate dilution calculations are essential in chemistry, pharmaceuticals, laboratory work, and various industrial processes where precise concentration control is required.
Tips: Enter initial percentage (%), initial volume (L), and final volume (L). All values must be valid (percentages ≥ 0, volumes > 0, final volume ≥ initial volume).
Q1: Can this formula be used for any concentration unit?
A: Yes, the formula works for any consistent concentration units (%, mg/mL, M, etc.) as long as the same unit is used for both initial and final concentrations.
Q2: What if I need to convert between different volume units?
A: Ensure all volume measurements are in the same units before calculation, or convert them appropriately (e.g., mL to L by dividing by 1000).
Q3: Does this formula account for density changes?
A: For most practical purposes with dilute solutions, density changes are negligible. For concentrated solutions, additional corrections may be needed.
Q4: Can I use this for serial dilutions?
A: Yes, but you'll need to calculate each dilution step separately and multiply the dilution factors for the overall dilution.
Q5: What's the maximum accuracy of this calculation?
A: The accuracy depends on the precision of your measurements. The formula itself is mathematically exact for ideal solutions.
