Question

The formula for determination of density of a cubic unit cell is:

• A. $\frac{a^3\times N_0}{Z\times M}gc{m}^{-3}$
• B. $\frac{Z\times N_0}{M\times a^3}gc{m}^{-3}$
• C. $\frac{a^3\times M}{Z\times N_0}gc{m}^{-3}$
• D. $\frac{Z\times M}{N_0\times a^3}gc{m}^3$

Answer 1

The correct option is D $\frac{Z\times M}{N_0\times a^3}gc{m}^3$

The formula for determination of density of cubic unit cell is $\rho =\frac{Z\times M}{N_0\times a^3}gc{m}^3$
$\rho =$ density
$Z=$ number of atoms per unit cell
$M=$ molecular weight
$N_0=$ Avogadro's number
$a=$ edge length
