Answer:
2 mL
Step-by-step explanation:
Step 1: Given data
- Initial concentration (C₁): 10 M
- 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
