The cubic unit cell of a metal (molar mass=63.55 g mol^(-1)) has an edge length of 362 pm. Its density is 8.92 g cm^(-3). The type of unit cell is

Answer»

primitive
face centered
body centered
end centered

Solution :`rho=(zM)/(N_(A)V)`
`z=(rhoN_(A)V)/(M)=(8.92xx6.02xx10^(23)XX(362)^(3)xx10^(-3))/(63.55)`
=4
`therefore` it has fcc unit cell.
