The orthorhombic, the value of

a,b,

and

c

are respectively

4.2\mathop \mathrm{A}\limits^ \circ ,6.8\mathop \mathrm{A}\limits^ \circ

and

8.3\mathop \mathrm{A}\limits^ \circ .

Given the molecular mass of the solute is 155 g

\mathrm{mo}{\mathrm{l}^{ - 1}}

and that of density is 3.3g/cc, the number of formula units per unit cell is

View answer and explanation

Correct option: C

Option C (4) is correct because the number of formula units per unit cell is calculated using the formula Z = (V x N x d) / m, resulting in approximately 4.
