How to Calculate Dilution

The dilution formula is a key concept in chemistry, used to calculate the concentration of a solution after it has been diluted. The formula is:

C1 * V1 = C2 * V2

Where:

• C1 is the initial concentration of the solution.
• V1 is the initial volume of the solution.
• C2 is the final concentration of the solution after dilution.
• V2 is the final volume of the solution after dilution.

To find the final concentration (C2), you can rearrange the formula as follows:

C2 = (C1 * V1) / V2

Example Calculation

Let's say you have a 12 M stock solution (C1) and you take 2 mL of it (V1). You then dilute it with water to a final volume of 10 mL (V2). To find the new concentration (C2), you would calculate:

C2 = (12 M * 2 mL) / 10 mL = 2.4 M

So, the final concentration of the solution is 2.4 M.
