Please discuss how you arrived at that -2.295 figure rather than directly give that answer. If all of you just wanted that f.uc.k.ing certificate without understanding the material, then what you will get is only certificate not the knowledge and experience...

**Chemistry**

The formula and explanation are given in the lecture video S23V2, in this case what you need to be cautious is the Z, Pt and Au are FCC structure, hence you need to draw the unit cell and its surrounding unit cell to get the idea of the coordination number.
