First, we need to calculate the atomic volume of the alloy.
00:04
So here we can use the formula, atomic volume is equal to 4 divided by 3 multiplied by pi multiplied by r raised to the power 3 where r is the atomic radius.
00:25
So this atomic volume would be equal to 4 divided by 3 multiplied by pi multiplied by 0 .125 raised to the power 3.
00:40
Upon solving this, we get the value of 0 .001953125 nanometer cube.
00:53
Next, we need to calculate the packing factor of the alloy.
00:56
For this, we use packing factor is equal to number of atoms per unit cell multiplied by the atomic volume and then all of this divided by the unit cell volume.
01:36
For bcc structure, the packing factor, let us denote it as pf.
01:44
So for bcc structure, the packing factor would be equal to 0 .68...
