# Problem: 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 m3 of a single Rh atom?

###### FREE Expert Solution

Recall:

Diameter:

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

Volume of a sphere:

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