Answer:

A) 4 atoms/unit cell

B) 7.31 g/cm^3

Explanation:

A) Determine the number of atoms in each unit cell

attached below is the detailed solution

number of atoms per unit cell ( n ) = 4 atoms/unit cell

B) Given atomic weight of indium = 114.82 g/mol

hence the theoretical density  = 7.31 g/cm^3

Attached below is a detailed solution of the question
