Answer:

0.01932 L

Explanation:

First we convert 105 mM to M:

  • 105 mM / 1000 = 0.105 M

Next we convert 552 mL to L:

  • 552 mL / 1000 = 0.552 L

Then we use the following equation:

  • C₁V₁=C₂V₂

Where:

  • C₁ = 3 M
  • V₁ = ?
  • C₂ = 0.105 M
  • V₂ = 0.552 L

We input the given data:

  • 3 M * V₁ = 0.105 M * 0.552 L

And solve for V₁:

  • V₁ = 0.01932 L
