First of all, let's have a look what all is given in the problem.
00:05
Given is some of the information is given.
00:09
That is like it is given that the lattice crystal structure is of fcc type.
00:15
Molar mass of the compound is also given.
00:18
Molar mass is given as 106 .4 gram per mole.
00:24
After that, it is given that the density is 12.
00:31
Density is given as 12.
00:35
So what we are supposed to find out is we need to find the radius or we have to find out.
00:43
So we know that there is a general formula that relates these density equals to zm by na into a cube, where a cube is the edge length, n is the vagetro number.
00:55
Now if we substitute all these values, density is given as 12, it is fcc lattice...
