    The answer to your question is pH = 4

    Explanation:

    Data

    Volume 1 = V1 = 1 ml = 0.001 l

    Concentration 1 = C1 = 0.1 M

    Volume 2 = V2 = 1 l

    Concentration 2 = C2 = ?

    Process

    1. - Find the new concentration of the solution

    C₁V₂ = C₂V₂

    Solve for C₂

    C₂ = C₁V₁ / V₂

    Substitution

    C₂ = (0.1 x 0.001) / 1

    Result

    C₂ = 0.0001 M

    2. - Find the pH of the solution

    Formula

    pH = - log[H⁺]

    Substitution

    pH = - log[0.0001]

    Simplification

    pH = 4
