I am now supposed to find the diameter in angstroms of an atom of gold. I get that I need to find the number of atoms of gold in 1 cm, therefore, it should be the cube root of 5.9 x10^22, which I have as roughly 3.89 x 10^7 atoms/cm. From here, I divided 1 by the above result to get the diameter, and got 2.6 Angstroms diameter.
