The formula for determination of density of unit cell is.

A

a3×NoN×Mgcm−3\frac{a^{3} \times N_{o}}{N \times M}gcm^{- 3}

B

N×Ma3×Nogcm−3\frac{N \times M}{a^{3} \times N_{o}}gcm^{- 3}

C

a3×MN×Nogcm−3\frac{a^{3} \times M}{N \times N_{o}}gcm^{- 3}

D

M×Noa3×Ngcm−3\frac{M \times N_{o}}{a^{3} \times N}gcm^{- 3}

Answer

N×Ma3×Nogcm−3\frac{N \times M}{a^{3} \times N_{o}}gcm^{- 3}

Explanation

Solution

Density of unit cell =N×mol.wt.(M)V(=a3)×avogadrono.(No)gcm−3= \frac{N \times \text{mol}.\text{wt}.(M)}{V( = a^{3}) \times \text{avogadrono.}(N_{o})}gcm^{- 3}
