Question

QUICKKKKK ill do 200+ points next question, how would you produce 1L of a .5 M KF solution, from a stock solution of 1 M KF

Answer 1

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.
