Dilution Calculator

In chemistry, biology, and laboratory work, dilution calculations are a common yet crucial task. Whether you are preparing solutions, conducting experiments, or working in a laboratory, accurately determining the correct concentrations and volumes is essential. Manual calculations can be prone to mistakes, especially when dealing with multiple solutions.

Our Dilution Calculator simplifies this process by allowing you to compute any of the four main dilution parameters—Initial Concentration (C1), Initial Volume (V1), Final Concentration (C2), or Final Volume (V2)—quickly and accurately. Based on the standard dilution formula C1×V1=C2×V2C1 \times V1 = C2 \times V2C1×V1=C2×V2, this online tool eliminates errors and saves valuable time.

How to Use the Dilution Calculator

Using this online tool is simple and intuitive. Follow these steps:

  1. Enter Known Values:
    Input the values for the parameters you already know. These can be the initial concentration (C1), initial volume (V1), final concentration (C2), or final volume (V2).
  2. Select the Unknown Parameter:
    Use the dropdown menu labeled “Calculate” to select which variable you want the calculator to solve:
    • Final Volume (V2)
    • Final Concentration (C2)
    • Initial Volume (V1)
    • Initial Concentration (C1)
  3. Click Calculate:
    Press the Calculate button. The result will appear below, along with the dilution formula for reference.
  4. Reset for New Calculation:
    Click the Reset button to clear all input fields and perform another calculation.

This straightforward interface ensures that anyone—from students to professional chemists—can quickly and reliably perform dilution calculations.

Examples

Here are practical examples to demonstrate how the Dilution Calculator works:

Example 1: Calculate Final Volume (V2)

Given:

  • Initial Concentration (C1) = 5 M
  • Initial Volume (V1) = 50 mL
  • Final Concentration (C2) = 2 M

Calculation:V2=C1×V1C2=5×502=125 mLV2 = \frac{C1 \times V1}{C2} = \frac{5 \times 50}{2} = 125 \, \text{mL}V2=C2C1×V1​=25×50​=125mL

The calculator instantly displays Final Volume (V2) = 125 mL.

Example 2: Calculate Final Concentration (C2)

Given:

  • C1 = 10 mg/mL
  • V1 = 20 mL
  • V2 = 50 mL

Calculation:C2=C1×V1V2=10×2050=4 mg/mLC2 = \frac{C1 \times V1}{V2} = \frac{10 \times 20}{50} = 4 \, \text{mg/mL}C2=V2C1×V1​=5010×20​=4mg/mL

The tool shows Final Concentration (C2) = 4 mg/mL.

Example 3: Calculate Initial Volume (V1)

Given:

  • C1 = 12%
  • C2 = 6%
  • V2 = 200 mL

Calculation:V1=C2×V2C1=6×20012=100 mLV1 = \frac{C2 \times V2}{C1} = \frac{6 \times 200}{12} = 100 \, \text{mL}V1=C1C2×V2​=126×200​=100mL

The calculator displays Initial Volume (V1) = 100 mL.

Example 4: Calculate Initial Concentration (C1)

Given:

  • V1 = 50 mL
  • C2 = 8 M
  • V2 = 100 mL

Calculation:C1=C2×V2V1=8×10050=16 MC1 = \frac{C2 \times V2}{V1} = \frac{8 \times 100}{50} = 16 \, \text{M}C1=V1C2×V2​=508×100​=16M

The result is Initial Concentration (C1) = 16 M.
