Answer:

2 mL

Explanation:

Step 1: Given data

  • Initial concentration (C₁): 10 M
  • Initial volume (V₁): ?
  • Final concentration (C₂): 0.1 M
  • Final volume (V₂): 200 mL

Step 2: Calculate the volume of the 10 M solution

We want to prepare a diluted solution from a concentrated one. we can calculate the volume of the initial solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂/C₁

V₁ = 0.1 M × 200 mL/10 M

V₁ = 2 mL
