We have to calculate the volume of a gold atom in cm^{3} units using the radius given (1.35 Å).

We have to **assume** that the *gold atom is spherical* in shape.

The **volume of a sphere **is calculated by this formula:

$\overline{){\mathbf{V}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{4}}{\mathbf{3}}{{\mathbf{\pi r}}}^{{\mathbf{3}}}}$

The radius of an atom of gold (Au) is about 1.35 Å.

If the atom is assumed to be a sphere, what is the volume in cm^{3} of a single Au atom?
