Answer:

a. 5.36x10⁻⁴ g/mL

b. 4.29x10⁻⁵ g/mL

Explanation:

As the units for concentration are not specified, I'll respond using g/mL.

a. We <em>divide the sample mass by the final volume</em> in order to <u>calculate the concentration</u>:

  • 0.268 g / 500 mL = 5.36x10⁻⁴ g/mL

b. We can use C₁V₁=C₂V₂ for this question:

  • 8.00 mL * 5.36x10⁻⁴ g/mL = C₂ * 100.00 mL
  • C₂ = 4.29x10⁻⁵ g/mL
