Answer:
79.0 mL
Explanation:
Given data
- Initial concentration (C₁): 10.0 M
- Final concentration (C₂): 1.00 M
- Final volume (V₂): 790.0 mL
In order to find the volume required of the concentrated solution, we will use the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂/C₁
V₁ = 1.00 M × 790.0 mL/10.0 M
V₁ = 79.0 mL
