Crystal Lattice Structures: Density Calculation 1

The video tutorial explains how to calculate the density of Gadolinium, which forms a hexagonal close packed structure. The atomic radius is given, and a conversion factor is used to express it in centimeters. The density formula for hexagonal close packed structures is applied, involving the atomic mass and Avogadro's number. The tutorial emphasizes the importance of using correct parentheses in calculations. The final density is calculated and rounded to 7.92 grams per cubic centimeter.

How do the units cancel out in the density calculation?
