# Problem: Polonium crystallizes with a simple cubic structure. It has a density of 9.3 g/cm3, a radius of 167 pm, and a molar mass of 209 g/mol.Use these data to estimate Avogadros number (the number of atoms in one mole).

###### FREE Expert Solution

A simple cubic unit cell is composed of a cube with one atom at each of its corners. # of atoms = 1 atom per 1 unit cell

volume of unit cell = 3.7259 x 10-23 cm3
