Answer -
Edge length,┬аa┬а=3.61 ├Ч 10тИТ8┬аcm
As the lattice is fcctype, the number of atoms per unit cell,┬аz┬а= 4
Atomic mass,┬аM =63.5 g molтИТ1
We also know that, NA┬а= 6.022 ├Ч 1023┬аmolтИТ1
Applying the relation:
┬а ┬а ┬а ┬а ┬а ┬а ┬а ┬а ┬а┬а
= 8.97 g cmтИТ3
The measured value ofdensity is given as 8.92 g cmтИТ3. Hence, the calculateddensity 8.97 g cmтИТ3┬аis in agreement with its measured value.
