Question

How can you determine the atomic mass of an unknown metal if you know its density and the dimension of its unit cell ? Explain.

Answer 1

Atomic mass of element

$\left(M\right)=\frac{d\times a^3\times N_A}{Z}$

where, d = density

$a^3=$ volume of the unit cell

$N_A$ = Avogadro's number

Z= number of atoms present in one unit cell.
