Original solution: C₁ = 7.23 M, V₁ = 26.8 mL
Diluted solution: C₂ = ? M, V₂ = 150.0 mL
For dilution of solution: C₁V₁ = C₂V₂
Then, C₂ = C₁ × (V₁/V₂)
Concentration of diluted solution, C₂ = 7.23 × (26.8/150.0) M = 1.29 M
Diluted solution: C₂ = ? M, V₂ = 150.0 mL
For dilution of solution: C₁V₁ = C₂V₂
Then, C₂ = C₁ × (V₁/V₂)
Concentration of diluted solution, C₂ = 7.23 × (26.8/150.0) M = 1.29 M
