    Specific gravity of the sample = 8.947

    Explanation:

    Specific gravity of a substance is defined as the density of that substance divided by the density of water.

    Density of water = 1000g/l

    Density of substance = mass/volume

    = 85/9.5 x 10^-3

    = 8947.37 g/l

    SG = 8947.37/1000

    = 8.947
