Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
=
