Dilution Formula:
| From: | To: |
The dilution formula calculates the final concentration of a solution after it has been diluted. It's a fundamental calculation in chemistry, biology, and medical laboratories where precise concentrations are required.
The calculator uses the dilution formula:
Where:
Explanation: The formula shows that the final concentration is equal to the initial concentration divided by the dilution factor. A higher dilution factor results in a more diluted solution.
Details: Accurate dilution calculations are essential for preparing solutions of specific concentrations, conducting experiments, administering medications, and ensuring consistent results in laboratory work.
Tips: Enter the initial concentration and dilution factor. Both values must be positive numbers. The calculator will compute the final concentration in the same units as the initial concentration.
Q1: What units should I use for concentration?
A: The units can be any concentration measurement (mg/mL, M, %, etc.) as long as the initial and final concentrations use the same units.
Q2: How do I calculate dilution factor?
A: Dilution factor = Total volume / Volume of stock solution. For example, if you add 1 mL of stock to 9 mL of diluent, DF = 10.
Q3: Can this formula be used for serial dilutions?
A: Yes, for serial dilutions, the overall dilution factor is the product of individual dilution factors.
Q4: What's the difference between dilution factor and dilution ratio?
A: Dilution factor is the reciprocal of the dilution ratio. A 1:10 dilution has a dilution factor of 10.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but accuracy depends on the precision of your measurements and technique when preparing the actual dilution.
