<u>Answer:</u> The density of the given element is
<u>Explanation:</u>
To calculate the edge length, we use the relation between the radius and edge length for BCC lattice:
where,
R = radius of the lattice = 0.17 nm
a = edge length = ?
Putting values in above equation, we get:
To calculate the density of metal, we use the equation:
where,
= density
Z = number of atom in unit cell = 2 (BCC)
M = atomic mass of metal = 56.08 g/mol
= Avogadro's number =
a = edge length of unit cell = (Conversion factor:
)
Putting values in above equation, we get:
Hence, the density of the given element is
