Question

i give you brainlist and 5. star also but first solve it step by step​

Answer 1

We know, p = n* atomic mass/N. * a ^3

or n = p* N.* A^3/ atomic mass

FOR Fe,

n = 7.86 * 6.023*10^23 * ( 286*10^-10) / 255.85 = 2

(i.e., cubic lattice of Fe is body centered)

For V,

n = 5.96*6.023*10^23*(301*10^-10)^3 / 509.4 = 2

(i.e., cubic lattice of V is body centered)

For Pd,

n = 12.16 * 6.023*10^23*(388*10^-10)^3 / 106.4 = 4

(i.e., cubic lattice of Pd is face centered)

For Al,

n = 2.70*6.023*10^23*(405 * 10^-10) ^3 / 26.96 = 4

(i.e., cubic lattice of Al is face centered)
