1.	A bcc element of density 10m3g/cm^3 has edge length of 314pm.Calculate atomic mass of the element
Answer» ANSWER: approximately 97 Explanation: d = 10.3 g/cm^3 a = 314 pm =314 x 10^-10 cm in CASE of bcc, z = 2 d=M x z / Na {AVOGADRO no} x a^3 M= Na x a^3 x d / z = 6.022 x 10^23 x 314 x 10 ^-10 x 10.3 / 2 = 97.381762 x 10^19

A bcc element of density 10m3g/cm^3 has edge length of 314pm.Calculate atomic mass of the element

Answer»

ANSWER: approximately 97

Explanation:

d = 10.3 g/cm^3

a = 314 pm =314 x 10^-10 cm

in CASE of bcc, z = 2

d=M x z / Na {AVOGADRO no} x a^3

M= Na x a^3 x d / z

= 6.022 x 10^23 x 314 x 10 ^-10 x 10.3 / 2

= 97.381762 x 10^19
