Explanation:
It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.
Therefore, in one simple cubic unit cell sharing of one atom is only
.
Hence, the total number of atoms in a unit cell will be as follows.
= 1
Thus, we can conclude that there is 1 calcium atom present in each unit cell.
Answer:
17
Explanation:
the atomic mass is away protons + neutrons, electrons are neglatable.
6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.

Hello there!
<span> Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms.
</span>Convert atoms to moles and you get:
<span>9.97x10^(-15) moles Co
</span>
Hope This Helps You!
Good Luck :)
