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
