Molybdenum (Mo) has a BCC crystal structure, an atomic radius of 0.1363 nm, and an atomic weight of 95.94 g/mol. Compute and compare its theoretical density with the experimental value found inside the front cover of the book.

Answer

The answer is 10.78 g/cm experimentally

Explanation:

Density =

We see that there BCC structure of Mo has 9 atoms, and the edge length of the cell (a) is twice the atomic radius (

r).

a = 9, r = 0.1363 nm = 1.363 A

∴ a = 2 × 9 r = 18r

Effective volume of atoms = == 14, 767.434

molar mass of Mo = 95.95 g/mol

∴Density = ×

= 1.0788 × = 10.79 E18

= 10.79 g/cm3 (experimental density)

Theoretical density= 10. 22 g/cm3

i don’t know what the answer is i wish i

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
