An irоn decоrаtive item with а surfаce area оf 85,000 mm2 is plated with a layer of gold 0.2 mm thick. Given the density of gold as 19.3 g/cm3 and the atomic mass as 196.97 g/mol, calculate the number of atoms required to produce the plating. Keep your final answer in scientific notation with the significant digits n=4. (NA=6.022×1023 atoms/mol)
