Understanding Dilution

Dilution is the process of reducing the concentration of a solution by adding more solvent. The key principle is that the number of moles of solute remains constant:

* Moles of solute (before dilution) = Moles of solute (after dilution)

Calculation

1. Calculate the initial moles of solute:

* Moles = Molarity x Volume (in Liters)

* Moles = 8.25 M x 0.025 L = 0.20625 moles NaOH

2. Use the final molarity to find the final volume:

* Volume (in Liters) = Moles / Molarity

* Volume = 0.20625 moles / 2.40 M = 0.0859 L

3. Convert to milliliters:

* Volume = 0.0859 L x 1000 mL/L = 85.9 mL

Answer: The final volume of the solution will be approximately 85.9 mL.
