    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
