Palladium crystallizes with a facecentered cubic structure. It has a density of 12.0 , a radius of 138 , and a molar mass of 106.42. What is Avogardo's number?

No units, no workee problem.

Density is 12.0 g/cm3, radius is 138 pm, and molar mass is 106.42 g/mol

Worked the same way as the previous post about solving for atomic mass except here you are given the atomic mass and the unknown is the 6.02 x 10^23. The remainder of the problem mirrors the other one.

See the previous post about converting pm to cm first.
