Answer :
Answer:
4 M
Explanation:
To answer this problem we can use the following formula:
- V₁C₁ = V₂C₂
Where the subscript 1 refers to the volume and concentration before diluting, and 2 refers to volume and concentration after diluting.
Meaning that in this case we can write:
- 50 mL * C₁ = 100 mL * 2 M
We can now solve for C₁:
- C₁ = 4 M
