The mass of one unit cell of Na is 7.63 × [tex]10^{-23}[/tex] g.

Formula for mass is, m = mole × atomic mass × [tex]\frac{atom per unit cell}{avogadro number}[/tex]

Here, mole = 1

atomic mass = 22.98 g/mol

Avogadro number = 6.022 × [tex]10^{23}[/tex]

atom per unit cell = 2, 1 atom is in body center and 1 in corner.

Put these values in formula, m = 1 × 22.98 × [tex]\frac{2}{avogadro number}[/tex]

m = 7.63 × [tex]10^{-23}[/tex] g

A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions. The figure below illustrates the relationship of a unit cell to the entire crystal lattice. Cubic crystal system is of three following types:-

Simple cubic
Face center cubic
Body center cubic
