Molar Volume of Sodium
If you assume that an atom is a hard sphere, you can estimate the average volume of space it occupies using basic geometry.
Question
Estimate the volume, V , of a sodium atom ( Na ) using its metallic radius of 186

The molar mass of Na is 22.99g
The density of solid sodium is 0.97g/cm^3
(22.99g/mol) / (0.97g/cm^3) = _____________
What are the units of the above value?
