We know that density is equal to mass divided by volume.
volume of a sphere = (4*pi*r^3)/3
given, density of gold =19.5g/cm
           radius of sphere = 0.25cm
volume of sphere= (4*3.14*0.25*0.25*0.25)/3
                            =0.015625cc
density=mass/volume
mass=density*volume
        =0.3046875g
