1. What is a 1:20 Dilution?

A 1:20 dilution means one part of the original solution is mixed with nineteen parts of diluent, resulting in a total volume twenty times the original. This reduces the concentration by a factor of 20.

2. How Does the Calculator Work?

The calculator uses the simple dilution formula:

Where:

• \( C_1 \) — Initial concentration (mol/L or other units)
• \( C_2 \) — Final concentration after dilution

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, medical testing, and pharmaceutical preparations to achieve desired concentrations.

4. Using the Calculator

Tips: Enter the initial concentration in any consistent units (e.g., mol/L, mg/mL). The result will be in the same units as your input.

5. Frequently Asked Questions (FAQ)

Q1: How do I prepare a 1:20 dilution in practice?
A: Mix 1 mL of stock solution with 19 mL of diluent, or scale proportionally for different volumes.

Q2: Can I use this for any concentration units?
A: Yes, as long as you're consistent (both input and output will be in the same units).

Q3: What's the difference between 1:20 and 1/20 dilution?
A: They mean the same thing - both result in a 20-fold dilution of the original concentration.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact, but practical accuracy depends on precise measurement of volumes.

Q5: Can I calculate the reverse (concentrate from diluted)?
A: Yes, multiply the diluted concentration by 20 to find the original concentration.
