In this question, we have to calculate four different parts that is in the first part, we have to calculate volume of atoms.
00:07
In the second part, we have to calculate the volume of unit cell and in the third part, we have to calculate the value of density and in the fourth part, we have to calculate the atomic packing factor.
00:21
So for first part, we are having the values given that is radius is given to us which is equals to 0 .126 nanometer and we are also having the density value for this that is equivalent to 7526 kg divided by meter cube.
00:44
Now for calculating the volume of atoms that will be equals to 2 divided by 3, 4 pi r cube.
00:54
Putting the value in this and we will get the result that is 8 .373 r cube.
01:04
Now we know the value of r so we will get the result that is 0 .0167.
01:10
So this is v atoms we are having.
01:16
Now in the second part, we have unit cell volume and unit cell volume is calculated equals to a cube and a cube is 4r divided by root 3 cube and if we going to put the value in this formula, we will get 4 multiplied 0 .126 divided by root 3 raised to the power 3 and from here we will get the result which is v unit cell equal to 2 .46 multiplied 10 raised to the power negative of 23 centimeter cube.

This is the volume of unit cell...
