an element of atomic mass 98 5g/mol occurs in FCC structure if unit cell edge is 500pm and density - Chemistry - The Solid State

Question

an element of atomic mass 98 5g/mol occurs in FCC structure if
unit cell edge is 500pm and density is 5 22g/cm3, what
will be the value of avogadro constant?

We have a formula as, $d = \frac{z M}{a^{3} N_{A}}$ And we are given with d = 5 22g/cm3 M = 98 5g/mol a = 500pm = 5 x 10-8 cm z = 4 $N_{A} = \frac{z M}{a^{3} d_{}}$ NA = 4 x 98 5 /(5 x 10-8)3 x 5 22 = 5 916 x 1023
