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)` ].

Text Solution

Verified by Experts

`d=(ZxxM)/(a^(3)xxN_(A))`
=`(2xx7)/(3.52xx10^(-10))^(3)(6.022xx10^(23))`
