Answer:
theoretical density = 5.69 gm/cm^3
Explanation:
theoretical density is given as =[tex]\frac{atomic weight *n*10^{-6}}{N_a*a^{3}}[/tex]
where
[tex]a = \frac{4r}{\sqrt{3}}[/tex]
[tex]a = \frac{4*1.918*10^{-10}}{\sqrt{3}}[/tex]
[tex]a = 4.42 *10^{-10}[/tex]
N_a = 6.023 *10^{23}
for BCC n = 2
atomic weight = 148.09
so theoretical density is =[tex]\frac{148.06 *2*10^{-6}}{6.023 *10^{23}*[4.42 *10^{-10}]^{3}}[/tex]
theoretical density = 5.69 gm/cm^3
