The formula for determination of density of unit cell is

Options

A. `(a^(3) xx N_(0))/(N xx M) g cm^(-3)`
B. `(a^(3) xx M)/(N xx N_(0)) g cm^(-3)`
C. `(N xx M)/(a^(3) xx N_(0)) g cm^(-3)`
D. `(M xx N)/(a^(3)xx N) g cm^(-3)`

Answer

C

Explanation

Density of unit cell
`= (N xx "mol .wt."(M))/(V(= a^(2)) xx "Avogadro no." (N_(0))) g//cm^(-3)`
