Question

calculation is involving unit cell dimensions​

Answer 1

Answer:

With the help of geometry and attributes of unit cells, we can easily evaluate the volume of the unit cell. With volume and mass of atoms, we can also evaluate the density of the unit cell. A crystal lattice is represented in terms of unit cells; we can determine the density of crystal lattices by evaluating the density of unit cells.

Answer 2

Answer:

In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. According to this definition, noble gasatoms are considered molecules as they are monatomic molecules.
