Question

A metal (FW 311.8 g/mol) crystallizes into a face-centered cubic unit cell and has a radius of 2.86 Angstrom. What is the density of this metal in g/cm3

Answer 1

For a metal crystallizes into a face-centered cubic unit cell and has a radius of 2.86 Angstrom, the density  is mathematically given as

d=3.31g/cm

What is the density of this metal in g/cm3

Generally, the equation for the density  is mathematically given as

$d=\frac{2*m}{NA*a^3}\\\\Therefore\\\\d=\frac{2*295.6mol}{6.022*10^23*(6.67*10^{-3})}$

d=3.31g/cm

In conclusion, the density of this metal

d=3.31g/cm
