    HBr is a strong acid; therefore, it ionizes 100%. pH = -log(H^+).

    HBr is one of the strong acids. A strong acid ionizes 100%. Therefore, the H^+ concentration is the same as the HBr concentration. You are given the HBr concn, plug that into the equation, and out pops the pH. I shall be happy to check your answer.
