Calculation Steps
Given: C₁ = 100 M, C₂ = 10 M, V₂ = 100 mL
Using formula: C₁V₁ = C₂V₂
Calculation: V₁ = (C₂ × V₂) / C₁ = (10 × 100) / 100
Result: V₁ = 10.000 mL stock solution
Solvent volume: V₂ – V₁ = 100 – 10 = 90.000 mL

⚗️ Dilution Basics
Dilution is the process of reducing the concentration of a solute in a solution by adding more solvent. The key principle is that the amount of solute remains constant while the total volume increases.
C₁V₁ = C₂V₂
This equation states that the amount of solute before dilution equals the amount after dilution.
🧫 Dilution Factor
The dilution factor (DF) represents how much a solution has been diluted. It’s the ratio of the initial concentration to the final concentration.
DF = C₁ / C₂ = V₂ / V₁
A 1:10 dilution means 1 part stock solution mixed with 9 parts solvent, giving a dilution factor of 10.
