Hi, this is a video based on crystal structure.
00:05
So, crystal structure is the regular repeated arrangement of atoms.
00:11
The most common type of crystal structures are simple cubic, face center and body centered.
00:36
In the first step, we have to calculate the density of the alloy.
00:47
Density of alloy is calculated by the formula.
00:51
Density of alloy is equal to 1 divided by mass fraction of the a divided by density of a plus mass fraction of b divided by density of b.
01:27
On substituting for above equation we have 1 divided by mass fraction of metal a is 12 .5 % divided by density of a is 4 .27 gram per cmq.
01:46
So we have percentage and density of mass fraction of metal b is 87 .5 divided by density of metal b is 6 .35.
01:59
In both the numerators of the denominator we have percentage.
02:06
So it is my whole equation is multiplied by 100.
02:14
Calculating the density of alloy becomes 5 .985 gram per cm cube.
02:29
In the second part, we have to calculate the mass of the alloy.
02:38
The mass of the alloy is even by 1 divided by mass fraction of a divided by atomic weight of a plus mass fraction of b divided by atomic weight of b...
