What volume of concentrated nitric acid (15.0M) is requiredfor
seraphim [82]

Answer:

0.133 mL

Explanation:

Given data

  • Initial concentration (C₁): 15.0 M
  • Initial volume (V₁): to be determined
  • Final concentration (C₂): 0.001 M
  • Final volume (V₂): 2.00 L

We can find the volume of the concentrated solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.001 M × 2.00 L / 15.0 M

V₁ = 1.33 × 10⁻⁴ L = 0.133 mL
