Solid State

An atomic substance A of molar mass \(12 \mathrm{~g} \mathrm{~mol}^{-1}\) has a cubic crystal structure with edge length of \(300 ~\mathrm{pm}\). The no. of atoms present in one unit cell of \(\mathrm{A}\) is ____________. (Nearest integer)

Given the density of \(\mathrm{A}\) is \(3.0 \mathrm{~g} \mathrm{~mL}^{-1}\) and \(\mathrm{N}_{\mathrm{A}}=6.02 \times 10^{23} \mathrm{~mol}^{-1}\)
