Answer:
A. 444.5 pm
Explanation:
We know that:
i.e.
in a face-centered cubic crystal, the number of atoms per unit cell is (n) = 4
The molar mass of manganese (II) oxide ![[Mn(11)O] = 70.93 \ g/mol](https://tex.z-dn.net/?f=%5BMn%2811%29O%5D%20%3D%2070.93%20%5C%20g%2Fmol)
Density 
is given as 5.365 g/cm³
Avogadro constant 
= 6.023 × 10²³ atoms/mol
∴
Making th edge length "a" the subject, we get:
![a= \sqrt[3]{8.78 \times 10^{-23} \ cm^3}](https://tex.z-dn.net/?f=a%3D%20%5Csqrt%5B3%5D%7B8.78%20%5Ctimes%2010%5E%7B-23%7D%20%5C%20cm%5E3%7D)
a = 4.445 × 10⁻⁸ cm
a = 444.5 pm
Answer:
Standing still not movable
Explanation:
Meaning that it has stayed the same
Answer:
1 mole of atoms contains 6.022×1023 atoms. Thus, 0.2 mole of sodium element has 12.044×1022 atoms in it.
