A. 1.0 L of a 4.0 M HNO3 solution is added to water so that the final volume is 8.0 L.
B. Water is added to 0.25 L of a 6.0 M NaF solution to make 2.0 L of a diluted NaF solution.
Thanks.

✔ 最佳答案
A.C₁V₁ = C₂V₂
(4.0 M) × (1.0 L) = C₂ × (8.0 L)
Final concentration, C₂ = 4.0 × (1.0/8.0) M = 0.5 M
B.
C₁V₁ = C₂V₂
(6.0 M) × (0.25 L) = C₂ × (2.0 L)
Final concentration, C₂ = 6.0 × (0.25/2) M = 0.75 M
