Answer:
We will take the 0.5 L from the 1M stock solution of KF inorder to form 0.5 M KF of 1L.
Explanation:
Given data:
Final volume = 1L
Final molarity = 0.5 M
Initial molarity = 1 M
Initial volume = ?
Solution:
Formula:
M₁V₁ = M₂V₂
1 M × V₁ = 0.5 M ×1L
V₁ = 0.5 M ×1L /1 M
V₁ = 0.5 L
We will take the 0.5 L from the 1M stock solution of KF inorder to form 0.5 M KF of 1L.
