79.0 mL

Explanation:

Given data

Initial concentration (C₁) : 10.0 M Initial volume (V₁) : ? 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
