Question

The density of chromium is 7.29 cm s. If
the unit cell is a cube with edge length of
289 pm, determine the type of the unit coll.
[-Atomic mas of cr = 52 g
mol
]
​

Answer 1

Answer:

density= z M /a3 * avogadro no. (Na)

z= ?? (no. of atom per unit cell)

z = p *a3 *Na/ M

= 7.29 *( 2.89*10^-8 )³ * 6*10^23/ 52

=
