Stock solution: C₁ = 0.020 M, V₁ = 10.0 ml
Diluted solution: C₂ = ? M, V₂ = 25.0 ml
Dilution: C₁V₁ = C₂V₂
Then, C₂ = C₁ × (V₁/V₂)
Molarity of diluted solution, C₂ = (0.020 M) × (10.0/25.0) = 0.0080 M
Diluted solution: C₂ = ? M, V₂ = 25.0 ml
Dilution: C₁V₁ = C₂V₂
Then, C₂ = C₁ × (V₁/V₂)
Molarity of diluted solution, C₂ = (0.020 M) × (10.0/25.0) = 0.0080 M
