Q. The figure below shows a unit cell of the mineral perovskite (the titanium atom is at the centre of the cube). Which of the following is a correct chemical formula for this mineral?Chemistry Question Image

The Solid State

Solution:

Effective number of $Ca = 8 \times \frac{1}{8} = 1$
Effective number of $Ti = 1 \times 1 = 1$
Effective number of $O = 6 \times \frac{1}{2} = 3$
$\therefore $ Formula $ = CaTiO_3$
