Answer any five of the following questions. Lithium metal has a body – InterviewSolution

1.	Answer any five of the following questions. Lithium metal has a body centred cubic lattice structure with edge length of edge unit cell 352 pm. Calculate the density of lithium metal. [Given: Atomic mass of Li = 7 "gmol"^(-1) , N_(A) = 6.022 xx 10^(23) atoms mol""^(-1) ].
Answer» SOLUTION :`d=(ZxxM)/(a^(3)xxN_(A))` =`(2xx7)/(3.52xx10^(-10))^(3)(6.022xx10^(23))`
