Question

Use these data to estimate Avogadro's number.

Palladium crystallizes with a face-centered cubic structure. It has a density of 12.0g/cm^3 , a radius of 138 pm , and a molar mass of 106.42 g/mol .
a = 4r/(2<sup>1/2</sup>
volume = a<sup>3</sup>
mass unit cell = volume x density
Then N = atoms/unit cell x atomic mass/mass unit cell.
I calculated close to 6E23.
