    8.597 g/cm³.

    Explanation:

    The density of the alloy = [ (density of Cu) (Cu % / 100) + (density of Zn) (Zn % / 100) ]

    Density of Cu = 8.95 g/cm³,

    % of Cu = 80.5 %,

    Density of Zn = 7.14 g/cm³,

    % of Zn = 19.5 %.

    ∴ The density of the alloy = [ (density of Cu) (Cu % / 100) + (density of Zn) (Zn % / 100) ] = [ (8.95 g/cm³) (80.5 / 100) + (7.14 g/cm³) (19.5 / 100) = [7.205 g/cm³ + 1.39 g/cm³] = 8.597 g/cm³.
