General Formula:
| From: | To: |
Dilution calculation is a fundamental concept in chemistry and laboratory work that determines the final concentration of a solution after it has been diluted with additional solvent. The general formula expresses the relationship between initial and final concentrations and volumes.
The calculator uses the dilution equation:
Where:
Explanation: The equation shows that the final concentration is proportional to the initial concentration and the ratio of initial to final volumes.
Details: Dilution calculations are essential in laboratory settings for preparing solutions of desired concentrations, in medical fields for medication preparation, and in various industrial processes where precise concentration control is required.
Tips: Enter initial concentration in appropriate units, initial volume in liters, and final volume in liters. All values must be positive numbers greater than zero.
Q1: What units should I use for concentration?
A: The calculator accepts any concentration units (mg/mL, M, %, etc.) as long as you're consistent. The result will be in the same units as your initial concentration.
Q2: Can I use different volume units?
A: While the calculator uses liters, you can use any volume unit as long as both Vi and Vf are in the same units (mL, L, etc.).
Q3: What if my final volume is less than initial volume?
A: This would represent concentration rather than dilution, but the formula still applies mathematically.
Q4: How accurate are dilution calculations?
A: The calculation is mathematically precise. Actual accuracy depends on measurement precision of your initial values.
Q5: Can this be used for serial dilutions?
A: For serial dilutions, you would need to apply this formula sequentially for each dilution step.
