Find the simplest formula of a solid containing `A` and `B` atoms ia cubic arrangement In which `A` occuples corner and `B` the centre of the faces of unit cell. If the side length is `5 Å`, estimate the density of the solid assuming atomic weights of `A` and `B` as `60` and `90`, respectively.

To solve the problem, we will follow these steps: ### Step 1: Determine the number of atoms of A and B in the unit cell - **A occupies the corners** of the cubic unit cell. There are 8 corners in a cube, and each corner atom contributes \( \frac{1}{8} \) of an atom to the unit cell. \[ \text{Contribution of A} = 8 \times \frac{1}{8} = 1 \text{ atom} \] ...
