**Recall:**

Diameter:

$\overline{){\mathbf{d}}{\mathbf{=}}{\mathbf{2}}{\mathbf{r}}}$

Volume of a sphere:

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

An atom of rhodium (Rh) has a diameter of about 2.7x10^{-8 }cm.

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