Chemistry - Solid State Question with Solution | TestHub

Number of moles present in$1\mathrm{g}=\frac{1}{60}$

So number of formula units in$\frac{1}{60}$moles

$=\frac{1}{60}\times 6.023\times 10^{23}=10^{22}=10\times 10^{21}$

Since 4 formula units constitute a unit cell

So number of unit cells present

$=\frac{10}{4}\times 10^{21}=2.5\times 10^{21}$
