Explanation:
The given data is as follows.
Mass = 27.9 g/mol
As we know that according to Avogadro's number there are atom present in 1 mole. Therefore, weight of 1 atom will be as follows.
1 atoms weight =
In a diamond cubic cell, the number of atoms are 8. So, n = 8 for diamond cubic cell.
Therefore, total weight of atoms in a unit cell will be as follows.
=
=
Now, we will calculate the volume of a lattice with lattice constant 'a' (cubic diamond) as follows.
=
=
=
Formula to calculate density of diamond cell is as follows.
Density =
=
= 2918.1
or, = 0.0029 g/cc (as 1 )
Thus, we can conclude that density of given semiconductor in grams/cc is 0.0029 g/cc.
